A binuclear Zn(II) complex [Zn2(SDBA)2(DPA)2.2H2O] (1) (DPA = di-2-pyridylamine, H2SDBA = 4,4?- sulfonyldibenzoic acid) is synthesized and characterized using single crystal X-ray diffraction, IR spectroscopy, and elemental analysis. The single crystal X-ray diffraction analysis reveals that complex 1 is a binuclear zinc(II) complex. The binuclear molecules are further connected by three types of N?H..O, C?H..O, and O?H..O hydrogen bonds, generating a three-dimensional supramolecular structure. Meanwhile, S?O..pi interactions further consolidate the three-dimensional supramolecular framework of 1. In addition, the thermal stability and luminescent properties of the title complex are briefly investigated. The luminescence measurements reveal that complex 1 exhibits fluorescent emission in the solid state at room temperature.

N,N-bis(carboxymethyl)-1-adamantylamine acid (H2BCAA) or N-(1-adamantyl)-iminodiacetic acid forms zwitterions that are intra-stabilized by a ‘bifurcated’ N+-H…O(carboxyl)2 interaction. In the crystal, both half-protonated carboxyl groups of H2BCAA ± are involved in linear O-H…O intermolecular bridges of 2.46 A. In the studied BCAA-CuII derivatives, the iminodiacetate-moiety of the BCAA chelating ligand exhibits a mer-NO2 conformation in [Cu(BCAA)(H2O)2] (1) and [Cu(BCAA)(Him)]2 (2), but fac-O2+N(apical) conformation in Cu(BCAA)(bpy)(H2O)]·3.5H2O (3) [Him = imidazole, bpy =2,2?-bipyridine]. In clear contrast, dipyridylamine (dpya), as auxiliary ligand, seems to be unable to promote the fac-O2+N(apical) conformation in BCAA, as reveal the structures of two new salts with the trinuclear cation [(dpya)2Cu-mu2-Cu(BCAA) 2-Cu(dpya)2]2+ and the anions [Cu(BCAA) 2]2- (4) or NO3- (5), respectively.

The preparation, crystal structures and magnetic properties of two copper(II) complexes with di-2-pyridylamine (dpa) as end-cap ligand and azide (1) and cyanate (2) as bridging groups, [Cu(dpa)(N3)2]n (1) and [Cu2(dpa)2(NCO)4] (2), are reported. Compound 1 consists of uniform chains of copper(II) ions bridged by single mu-1,1-azido groups whereas that of compound 2 is made up of centrosymmetric dicopper(II) units with double mu-1,1-N-cyanate bridges, the other two cyanate groups acting as terminal ligands. The copper atoms in 1 and 2 are five-coordinated with two nitrogen atoms of a bidentate dpa ligand (1 and 2), one nitrogen atom from a terminally bound azide (1)/cyanate (2) and two other nitrogens from two azide (1)/cyanate (2) bridges building intermediate square pyramidal/trigonal bipyramidal (1) and distorted square pyramidal (2) surroundings. The values of the copper-copper separation through the double end-on azido (1) and cyanato (2) bridges are 3.8556(4) and 3.5154(5) A?, respectively. Variable-temperature magnetic susceptibility measurements show the occurrence of weak magnetic interactions in both complexes being antiferromagnetic in 1 [J = -4.60 cm-1, the Hamiltonian is defined as over(H, ?) = – J ?i over(S, ?)i · over(S, ?)i + 1] and ferromagnetic in 2 [J = +3.14 cm-1 with over(H, ?) = – J over(S, ?)1 · over(S, ?)2]. The magnitude and nature of these magnetic interactions are discussed in the light of the respectives structures and they are compared with those reported for related systems.

Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11. In a Article，once mentioned of 499-40-1, HPLC of Formula: C12H22O11

A series of divalent nickel and copper complexes and a series of mixed-ligand nickel(II) chelates have been prepared and characterized. The general formula of the complexes is [cation]2[M(1,1-dithiolate) 2] (M = Ni(II), Cu(II)), and that of the mixed-ligand is [Ni(enR)(SS)], containing the dianion of 1,1-dithiolate derivatives and an N-alkyl- or N-phenyl-substituted 1,2-diaminoethane or a bidentate nitrogenous base, enR. The structures of the complexes, both in the solid state and in solution, have been determined by IR, UV-Vis, room temperature magnetic and electrical conductance measurements. The MS4 chromophoric group is common to all of the homoleptic complexes and contains two four-membered chelate rings. The MS2N2 chromophoric group is common to the mixed-ligand complexes. The 1,1-dithiolate derivatives are substituted isomaleonitriles of the formula Y(CN)CCS22-, where Y = CONH2 (1-cyano-1-carboamido-2,2-ethylenedithiolate, CCED); COOEt (1-cyano-1- carboethoxy-2,2-ethylenedithiolate, CED); ph (1-cyano-1-phenyl-2,2- ethylenedithiolato, CPD) and Cl-ph (1-cyano-1-chlorophenyl-2,2- ethylenedithiolate, CCPD). X-ray structural analyses were performed for three compounds. The tetrabutylammonium(1-cyano-1-chlorophenyl-2,2-ethylenedithiolato) copper(II) complex consists of three molecules per unit cell. The copper atom lies on a crystallographic center of symmetry which requires the CuS4 unit to be planar. The average Cu-S bond length is 2.204 A. In the unit cell of the complex [(2,2?-bipyridine)(1-cyano-1-phenyl-2,2- ethylenedithiolato)nickel(II)] there are six nickel atoms. In the immediate vicinity of each nickel atom exist two sulfur and, at a shorter distance, two nitrogen atoms. The molecules in the unit cell are arranged in pairs, each pair forming two weak intermolecular Ni?S bond interactions at a distance of 3.617 A. In the novel sulfur-rich ligand 5-amino-4-(4-chlorophenyl)-[1,2] dithiole-3-thione, three carbon atoms are linked with two sulfur atoms forming a five-membered ring. All observed intramolecular bond lengths in the sulfur ring indicate delocalization of the pi-electron system.

A series of cation-anion complexes derived by 2,2?-dipyridylamine (Hdpa) and carboxylate ligands with formulas [Ni(Hdpa)2(CH 3COO)]Cl(CH3OH) (1), [Co(Hdpa)2(CH 3COO)]Cl(CH3OH) (2), [Ni(Hdpa)2(CH 3CH2CH2COO)]Cl (3), [Co(Hdpa) 2(CH3CH2CH2COO)]Cl (4), [Ni(Hdpa)2(C6H5COO)]Cl (5), and [Co(Hdpa) 2(C6H5COO)]Cl (6), were synthesized and characterized by IR, elemental analysis, MS(ESI), TG analysis, UV-Vis, and fluorescence spectra. X-ray single crystal structural analysis showed that the coordination geometries of metal ions in these complexes are similar and they are cation-anion species. The hydrogen-bonding structures are 1-D chains through the N-H…Cl bonds. There are weak stacking interactions between pyridine rings in 1-4, while there are no stacking interactions in 5 and 6. We have investigated the transesterification of phenyl acetate with methanol catalyzed by 1-6 under mild conditions; 1-4 are homogeneous catalysts while 5 and 6 are heterogeneous catalysts due to their poor solubility in methanol. Cobalt complexes exhibit higher catalytic activities than corresponding nickel complexes. Complex 4 is the best catalyst of these six complexes.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. Introducing a new discovery about 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, Application In Synthesis of (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal.

The mixture of 2, 2?-bipyridylamine, 2, 2?’-bipyridine, 1, 10phenanthroline, 1, 2-phenylendiamine, and 1, 4-phenylendiamine each with LiBH4 and NaBH4 in a 1:1 molar ratio in THF yields seven new complexes of the type MBH4-L-THF and one complex of the type MBH4-L. These compounds were characterized by IR and NMR spectroscopy and X-ray single-crystal structure determinations. In the solid state, the [BH4]- group is bidentate, as deduced from the stretching patterns observed in IR spectra and confirmed by X-ray single-crystal structure analysis. NMR spectroscopy showed that all amines act as bidentate ligands and are symmetrically coordinated to the metal cation. Complexes LiBH4-2, 2?bipyridine-THF (1), NaBH4-2, 2?-bipyridine-THF (2), LiBH4-1,10-phenanthroline-THF (3), and NaBH4- 1,10-phenanthroline-THF (4) have a discrete molecular structure, whereas the complexes LiBH4-1,2-phenylendiamine-THF (5), NaBH4-1, 2-phenylendiamine-THF (6), LiBH4-2, 2?-dipyridilamine (7), and LiBH4- 1, 4-phenylendiamine-THF (8) have polymeric structures in the solid state. N-borane-dipyridylamlne adduct 9 was isolated from, an aged, solution of 7. IR spectroscopy of the new complexes showed that the structures of complexes 1, 3, 4, and 6 are maintained in the solid state and in solution. A rotational barrier for the [BH4]- group of less than 38 KJ mol-1 was estimated for some of the new complexes.

Cobalt(III) complexes of 2,2?-dipyridylamine (dpamH) and the ligands salicylaldehyde (X-saloH) and their corresponding salicylic acids (X-salicylato), where X = CH3, Cl and Br, under the general formula [Co(X-salo)(X-salicylato)(dpamH)] (1?3), were synthesized in situ by slow oxidation in air of ethanolic solutions of the complexes [Co(5-X-salo)2(dpamH)]. The new compounds were characterized by physicochemical methods and by spectroscopy (IR, 1H-NMR and UV?Vis). The octahedral geometry around Co3+ion and the bidentate chelating mode of the salicylaldehydato anion (X-salo?) and the salicylato di-anion (X-salicylato2?) were proved by single-crystal X-ray diffraction analysis for the complex [Co(5-CH3-salo)(5-CH3-salicylato)(dpamH)] (1). The variable-temperature (76?303 K) magnetic susceptibility measurements showed a diamagnetic nature of the complexes, in accordance with their molecular structure. The simultaneous TG/DTG?DTA technique was used to analyze their thermal behavior under inert and/or oxygen atmosphere, with particular attention to determine their thermal degradation pathways, which was found to have a multi-step nature, accompanied by the release of the ligand molecules.

The role of hetero-atom manipulation/hetero-aryl group insertion in the triarylamine to obtain hetero triarylamine as a donor in highly efficient photosensitizers was investigated to study the structure-efficiency relationship in dye-sensitized solar cells (DSSCs). A newly synthesized sensitizer was explored containing N-phenyl-N-(pyridin-2-yl) pyridine-2-amine (DPPA) and N-(pyridin-2-yl)-N-(thiophen-2-yl) pyridine-2-amine (DPTA) as the donor along with a strong electron-withdrawing cyano group (-CN) as the auxiliary acceptor group and cyanoacetic acid and rhodamine-3-acetic acid as anchoring groups. The triphenylamine donor was manipulated for the first time with the insertion of a nitrogen atom in the aryl ring for DSSCs. These hetero-aryl-based sensitizers showed a significant improvement in the photophysical as well as photovoltaic performance. The replacement of cyanoacetic acid by rhodanine-3-acetic acid as an anchoring unit resulted in a significant red-shift in absorption as well as emission maxima. The methylene group in rhodanine-3-acetic acid interrupted the LUMO delocalization on the anchoring group in sensitizers DP3 and DP4, as shown by DFT calculations. The presence of cyanoacetic acid in sensitizers DP1 and DP2 showed effective charge transfer from HOMO to LUMO and efficient electron injection from LUMO to the conduction band of the TiO2 semiconductor. The sensitizer DP2 showed a maximum efficiency of 4.7%, a short-circuit current Jsc = 11.78 mA cm-2, an open-circuit voltage Voc = 0.608 V and a fill factor FF = 0.62. The enhanced efficiency of sensitizer DP2 was attributed to the presence of the strong electron-withdrawing cyanoacetic acid anchoring group and the presence of the thiophene linker at the N-aryl core.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11.

In order to seek for new compounds with antitumor activity, our research group is focused on copper complexes with mixed ligands. This work presents the synthesis and characterization of eight compounds with general formula [Cu(iminodiacetate)(diimine)(H2O)x], with x = 0 or 1, and their cytotoxic activities against tumor cells. The chosen diimine ligands were: 2,2?-dipyridil-amine (bam), 2,2?-bipyridine (bipy), 4,4?-dimethyl-2,2?-bipyridine (dmb), 1,10-phenanthroline (phen), 4-methyl-1,10-phenanthroline (4met-phen), 5-nitro-1,10-phenanthroline (5nitro-phen), neocuproine (neo) and bathophenanthroline (batho). Compounds were characterized in solid state using FT-IR, TGA, DSC and single crystal X-ray diffraction analyses by which five new crystal structures were determined. Common features of the coordination scheme include fac-NO + O isomerism of the iminodiacetate (ida) ligand, except for the complex with neo where the ida presents mer-NO2 isomerism. The diimine ligand completes the equatorial plane for the facial isomers, with different degrees of distortion in the octahedral or square-based pyramid geometry depending on the diimine ligand, whereas the neo is perpendicular to the equatorial plane in the latter. Studies in solution, using EPR, UV?Vis spectroscopy and conductimetry, showed that the copper coordination observed in solid state is retained except for the batho complex. DNA interaction studies evidenced that the complexes bind to this biomolecule, inducing different conformational changes. Biological experiments evidenced that all complexes induce cell death in the cell line MDA-MD-231 (metastasic breast cancer line). [Cu(ida)(neo)] and [Cu(ida)(batho)] presented the highest activity. Taken all these data together we propose that [Cu(ida)(neo)] and [Cu(ida)(batho)] are good candidates for further studies in vitro and in vivo.
