Hydrothermal synthesis was exploited to provide three compounds of the VxOy/Cu/imine family. Compound 1, [{Cu2(2, 2?-dpam)4}V4O12] is molecular, while [{Cu2(OH)(o-phen)2}V3O9] (2) and [{Cu2(4,4?-bpy)3(H2O)2}V 4O12]¡¤5H2O (3¡¤5H2O) are one-dimensional and three-dimensional, respectively. The copper-imine components are shown to be critical structural determinants that assume charge-compensating and space-filling roles, as well as providing ligand geometric and steric constrains, as well as flexible metal coordination geometry.

A series of the half-sandwich Ir(III) and Rh(III) complexes [M(eta5-Cpx)(dpa)X]PF6 (M = Ir for 1?6 and Rh for 7?12) containing N-(pyridin-2-yl)pyridin-2-amine (2,2?-dipyridylamine, dpa), pentamethylcyclopentadienyl (Cp*; for 1?5 and 7?11) or 1,2,3,4-tetramethyl-5-phenylcyclopentadienyl (Cpph; for 6 and 12) ring, and various monodentate ligands (X), specifically Cl? (for 1, 6, 7 and 12), Br? (for 2 and 8), I? (for 3 and 9), valproato (VP; for 4 and 10) or 4-phenylbutyrato (PB; for 5 and 11), was prepared. The complexes were thoroughly characterized by elemental analysis, IR and NMR spectroscopy and mass spectrometry. A single-crystal X-ray analysis was performed for complex [Ir(eta5-Cpph)(dpa)Cl]PF6 (6), revealing a pseudo-octahedral piano-stool geometry with a bidentate N,N?-coordinated dpa ligand, a penta-hapto coordinated Cpph ring and a monodentate chlorido ligand. The crystal structure of complex 6 is stabilized by N?H?F, C?H?F, C?H?Cl, C?H?C and C?F non-covalent contacts. Complexes 1?12 were screened for their in vitro cytotoxicity against the A2780 human ovarian carcinoma cell line. The best-performing iridium(III) complex 6 showed markedly higher activity (IC50 = 23.5 muM) than complexes 1?3, 5, 9 and 12, whose IC50 ranged from 68.7 to 87.1 muM. Iridium(III) complex 4 and rhodium(III) complexes 7, 8, 10 and 11 were inactive against the A2780 cells in the tested concentration range (IC50 > 100.0 muM). The chlorido complexes 1, 6, 7 and 12 were studied by 1H NMR spectroscopy for their hydrolytic stability in the 20% DMF-d7/80% D2O and 20% MeOD-d4/80% D2O mixture of solvents, revealing Ir(III) complexes 1 and 6 as stable, while Rh(III) complexes 7 and 12 partially hydrolysed in the used medium. Moreover, hydrophobicity (lipophilicity) of complexes 1?12 was studied by an octanol/water partition (logP).

A new potent anticancer agent of 2,2?-dipyridylamine8-hydroxyquinolinatopalladium(II) chloride, [Pd(dpa)(8Q)]Cl titled as PDQ, was synthesized by the reactions of Na2PdCl4 with the organic compounds of 2, 2?-dipyridylamine (D) and 8-hydroxyquinoline (Q). Also, the prepared complex was characterized by elemental analyses, FTIR, NMR spectroscopies and conductivity measurements. The characterization results were found in consistent with the proposed structure of PDQ and DFT methodology confirmed the experimental results. The cytotoxicity evaluation of complex against human chronic myelogenous leukemia (K562) cancer cells demonstrated that the CC50 value of PDQ (22 muM) was comparable with carboplatin and better than some palladium complexes, which were reported as potential anticancer agents. Moreover, PDQ-DNA binding properties were extensively performed by UV?vis, fluorescence, CD spectroscopies and viscosity measurement in physiological condition. Molecular docking technique was performed to provide more insights on binding mode. Overall, all evidence revealed that, PDQ spontaneously binds to DNA with intercalation mode and static mechanism.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety 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, you can also check out more blogs about499-40-1

A new ferrocene-containing dicarboxylate ligand, L = 5-ferrocene-1,3-benzenedicarboxylic acid, has been prepared. Self-assembly of L, M(II) salts (M = Co and Zn) and chelating ligands dpa or phen (dpa = 2,2?-dipyridylamine and phen = 1,10-phen) gave rise to four new coordination polymers {[Co(L)(dpa)] ¡¤ 2MeOH}n (1), {[Zn(L)(dpa)] ¡¤ 2MeOH}n (2), {[Co(L)(phen)(H2O)] ¡¤ MeOH} (3), [Zn(L)(phen)(H2O)] ¡¤ MeOH (4). The isostructural complexes 1 and 2 possess 1D helical chain structures with 21 screw axes along the b-direction, and the right- and left-handed helical chains are alternate arrayed into 2D layer structures through hydrogen-bonding interactions; while isostructural complexes 3 and 4 are 1D linear chain structures with phen and ferrocene groups of L as pendants hanging on the different sides of the main chain. A structural comparison of complexes 1-4 demonstrated that the characteristics of subsidiary ligands and slight difference in coordination models of L play very important role in the construction of the complexes. In addition, the redox properties of complexes 1-4, as well as the magnetic properties of complexes 1 and 3 are also investigated.

Treatment of Cu2(OAc)4¡¤2H2O with 2,2?-dipyridylamine (dpa) in 1:2 molar ratio in MeCN-H2O results neutral [Cu(OAc)2(dpa)]¡¤2H2O (1) which on subsequent treatment with 1 equiv of NaBF4 affords [Cu(OAc)(dpa)2]BF4 (2). The complexes are characterized using microanalytical, spectroscopic, magnetic, thermal, electrochemical, and other physicochemical results. Electrochemical electron transfer study of 1 and 2 in MeCN solutions show a reductive response presumably due to copper(II)-copper(I) couple. Thermal study (TG-DTA) of 1 reveals a weight loss of 9.21% at 70-85 K corresponding to two crystalline water molecules. Structures of 1 and 2 are solved by X-ray diffraction study. Compound 1 adopts a distorted octahedral CuN2O4 environment coordinated through two N atoms of dpa and four O atoms of two chelating acetates with elongated axial bonds. In 2, copper(II) is ligated by four N atoms of two dpa units and two O atoms of an acetate in chelating fashion resulting a cationic core of [Cu(OAc)(dpa)2]+. Crystal packings show that mononuclear units of 1 self-assemble through cooperative hydrogen bonds and pi…pi interaction and of 2, through hydrogen bonds along with C-H…pi interaction leading to 2D sheets. Both the complexes show high-energy intraligand 1(pi…pi*) fluorescence and intraligand 3(pi…pi*) phosphorescence in glassy solutions (DMF at 77 K).

The crystal structures of three representative complexes have been determined. The dinuclear-oxalate bridged compounds [Cu(dpyam) 4(C2O4)](ClO4)2(H 2O)3 (1) and [Cu2(dpyam)4(C 2O4)](BF4)2(H2O) 3 (2) crystallize in the non-centrosymmetric triclinic space group P1 which are isomorphous and isostructural. The compound [Cu 2(dpyam)2(C2O4)(NO3) 2((CH3)2SO)2] (3) crystallizes in the centrosymmetric monoclinic space group P1 with all Cu-oxalate contacts in the equatorial plane. All three complexes contain six-coordinate copper centres bridged by planar bis-didentate oxalate groups from the equatorial position of one chromophore to the equatorial position of the other one. Both chromophores in 1 and 2 exhibit the compressed octahedral Cu(II) geometry, while 3 displays an elongated octahedral Cu(II) environment. The IR, ligand field and EPR measurements are in agreement with the structures found. The magnetic susceptibility measurements, measured from 5 to 280 K, revealed a very weak ferromagnetic interaction between the Cu(II) atoms for compound 1 and 2, with a singlet-triplet energy gap (J) of 2.42 and 3.38 cm-1, for compounds 1 and 2, respectively. Compound 3 has a strong antiferromagnetic interaction with a J of -305.1 cm-1, in agreement with coplanarity of the magnetic orbitals.
