Two new compounds, [Cu(acac)(N3)(dpyam)] (1), (acac = acetylacetonate; dpyam = di-2-pyridylamine) and [Cu(mu-N3-kappaN1)(C2N3- kappaN1) (dpyam)]2 (2), have been synthesized and characterized by single-crystal X-ray diffraction and magnetic analyses. Compound 1 is a mononuclear compound in which each of two independent Cu(II) ions is penta-coordinated with a distorted square pyramidal geometry with distortion parameters tau = 0.21 and 0.16. In contrast, compound 2 is an azido-bridged dinuclear compound with monodentate dicyanamide anions and the Cu(II) ions display a distorted trigonal bipyramidal geometry with tau = 0.73 and end-on azido bridges providing an equatorial-axial position between the metal ions. The EPR spectra of powdered samples for 1 and 2 have also been investigated. Magnetic susceptibility measurements of compound 2 reveal a very weak ferromagnetic interaction between the Cu(II) ions with a J value of +5.8 cm-1.

A spectrophotometric and (1)H NMR kinetic study of the reactions of cis-[PtPh2(CO)(SEt2)] with an extended series of dinitrogen chelating ligands (N-N) of widely different steric and electronic properties has been carried out in dichloromethane solution. The contemporary presence in thestarting substrate of a labile (SEt2) and a relatively inert (CO) ligand in trans to firmly bonded phenyl groups makes it possible to distinguish three different reactivity patterns, according to the nature of the bidentate ligands used. Relatively stable open-ring species of the type cis-[PtPh2(CO)(N-N)] were isolated with the long chain ligand 1,4-diaminobutane and with N-phenyl-1,2-diaminoethane in which one of the two nitrogens exhibits very low basicity and considerable encumbrance. For the other dinitrogen ligands, the relative magnitude of the rates of attack atthe metal and of ring closure dictates whether the chelate formation isseen as a simple conversion of the starting complex into the final chelate [PtPh2(N-N)] or as a two stage process with evidence for the formation of an open-ring species. With rigid or highly sterically hindered ligands such as 2,2′-dipyridyl, 1,10-phenantroline, dicyclohexylethylenediimine or N,N,N’,N’-tetramethylethylenediamine a single stage process fromthe starting complex to the final chelate compound was observed. The rate determinig step is thought to involve slow dissociation of SEt2 from the complex followed by fast ring closing. With 1,2-diaminoethane, 1,3-diaminopropane, 2-aminomethylpyridine, 2-aminoethylpyridine, 2,2′-dipyridylamine and 2,2′-dipyridylsulfide a slow ring closure of the open-ring complex follows the fast entry of the first end of the ligand. The substrate shows a remarkable selectivity between the two nucleophilic ends of an unsymmetrical bidentate ligand with a clear preference for the most basic and the less hindered end. Open-ring reaction intermediates cis-[PtPh2(CO)(N-N)] were characterised in solution by their IR, (1)H and (13)CNMR spectra and their spectroscopic characteristic are compared to those of the parent amine and phosphine compounds. The final chelate compounds [PtPh2(N-N)] were either isolated as solids or characterised in solution.

The linear trirhodium compound, Rh3(dpa)4Cl 2 (1), and its one-electron oxidation product, [Rh 3(dpa)4Cl2]BF4 (2), have been synthesized and studied extensively. The magnetic measurement for compound 1 shows that it possesses one unpaired electron that is assigned to occupy the sigmanb orbital (2A2) by DFT calculations. Upon oxidation, a beta-spin electron of 1 is removed, that causes compound 2 to exhibit a triplet ground state. DFT calculations indicate that the two unpaired electrons of 2 occupy sigmanb and delta* orbitals (3B1), which is supported by 1H NMR spectrum. Unlike their isoelectronic analogues [Co3(dpa)4Cl 2] (3) and [Co3(dpa)4(Cl)2]BF 4 (4), both compound 1 and 2 do not display the spin-crossover phenomenon. The reason may be attributed to the relative large energy gap between 3B1 and open-shell singlet 1B 1 states.

The magnetostructural properties of 1-8 have been probed in detail by variable temperature magnetic measurements and crystallographic methods. 1-6 display mononuclear structures while 7 and 8 form 1-D chain structures. Complexes 4-6 have the potential to form 1D-chains via L2 bridging, but instead form mononuclear complexes. Magnetic studies show that complexes 1, 2, and 4 remain in the high-spin (HS) state at all temperatures. An aged, dry, powdered sample of 3 gives an abrupt HS to LS transition (T1/2 = 200 K), while a freshly prepared, powdered sample of 3·1.5H2O displays thermal hysteresis (Delta = 7 K). Complexes 5, 6 and 7 undergo a gradual spin transition with T1/2 values of 100 K, 150 K and 130 K, respectively. Cooperativity parameters are compared, with 3 showing cooperativity (positive C) and 5 and 6 showing anticooperativity. Photomagnetic LIESST (light induced excited spin state trapping) studies were performed on complexes 5 and 6 and reveal T(LIESST) values lower than 60 K. An attempt has been made to understand the electronic structure of complex 3 and its cooperativity behaviour using density functional methods, the calculations reproducing the sign and, in part, the magnitude of the cooperativity.

Crystallographic details for complexes [Cu(I)dipyam(CO)Cl] (1) and [Cu(II)dipyam(CH3CO2)Cl] (2) are as follows: complex 1, triclinic, space group P1- with a = 9.944(3), b = 9.450(3), c = 7.053(3)A, alpha = 69.50(2), beta = 91.81(2), gamma= 76.33(2)°, Z = 2; complex 2, triclinic, space group P1- with a = 10.093(3), b = 9.098(3), c = 7.444(2)A, alpha = 106.24(2), .bet a. = 96.91(2), gamma = 78.87(2)°, Z = 2. The dry carbonyl complexes are thermostable at 100°C or more, but their formation was reversible in solution even at room temperature. Thermal and chemical stabilities increase from the chloro to the iodo species. Among the acetatoderivatives the chloro and bromo mono-dipyam complexes were easily form ed, while the iodide gave preferentially the bis-dipyam complex. Each series of the complexes gave very similar IR spectra in the range 3800-250cm**-1. For the carbonyl derivatives the patterns of the far-IR 250-60 cm**-1 regions were shown and the nu(Cu-X) frequencies assigned.

Two dinuclear Cu(II) complexes of formula [Cu2(dpyam)2(mu-C2O4) (Cl)2] (1) and [Cu2(dpyam)2(mu-C2O4) (CF3SO3)2]n (2) (dpyam = di-2-pyridylamine) have been synthesized and their spectroscopic and magnetic properties characterized. The structure of 1 is made up of the centrosymmetric dinuclear [{Cu(dpyam)(Cl)}2(mu-C2O4)] units, while 2 contains chains of the dimeric [Cu2(dpyam)2(mu-C2O4) (CF3SO3)2] units linked by the triflate anions. The two copper atoms in both compounds are linked through a bis-didentate oxalato group leading to a metal-metal separation of 5.526(1) and 5.228(3) A?. The stereochemistry of the Cu(II) chromophore in 1 is approximately square pyramidal, while compound 2 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 350 K, revealed a very strong antiferromagnetic interaction between the Cu(II) atoms with a singlet-triplet energy gap (J) of -274 and -342 cm-1, for compounds 1 and2, respectively, in agreement with the coplanarity of the magnetic orbitals.

New copper(II) ternary complexes formulated as [Cu(N-N)BIG]ClO4, where BIG is deprotonated 2-((1H-benzimidazol-2-yl)methylamino)acetic acid and N-N represents 2,2?-bipyridine (1) or 4,4?-dimethyl-2,2?-bipyridine (2) or 5,5?-dimethyl-2,2?-bipyridine (3) or 1,10-phenanthroline (4) or 4,5-diazafluoren-9-one (5) or dipyridylamine (6), were synthesized and characterized using analytical and spectral methods. Complex 1 was characterized using single-crystal X-ray diffraction analysis and found to be monomeric in nature with distorted square pyramidal geometry. The binding interactions of 1?6 with calf thymus DNA were studied using UV?visible absorption and emission spectroscopy and viscosity measurements. The DNA cleavage ability of 1?6 with pUC19 DNA shows that the complexes can cleave DNA without any external agents. The ligand and complexes were investigated for their in vitro antibacterial activity against Bacillus subtilis and Staphylococcus aureus. The complexes showed enhanced antibacterial activities compared to the free ligand. Molecular docking studies of complexes 1?6 were made using Genetic Optimization of Ligand Docking (GOLD) software. The study indicated that LEU23, ASP25, ILE84, ASN144 and ARG87 of COX-2 were important for strong hydrogen bonding interaction with the complexes. Among the complexes, 2 showed the best docking result with COX-2. Cytotoxicity assay was performed using MTT reagent against human cervical cancer cells, human breast cancer cells and human lung cancer cells. The complexes were found to show moderate anticancer activity.

An article , which mentions 499-40-1, molecular formula is C12H22O11. The compound – (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 played an important role in people’s production and life.

The copper(II) complexes with the third-generation quinolone gatifloxacin (Hgati) were prepared in the absence or presence of the N,N?-donor heterocyclic ligands 2,2?-bipyridylamine (bipyam), 1,10-phenanthroline (phen) or 2,2?-bipyridine (bipy) and were characterized physicochemically and spectroscopically. The crystal structures of complexes [Cu(gati)(bipyam)Cl]·MeOH·H2O and [Cu(MOM-gati)(bipy)Cl]·MeOH·3H2O (MOM = methoxymethyl) were determined by X-ray crystallography. The antimicrobial activity of the compounds was tested against four different microorganisms (Escherichia coli, Xanthomonas campestris, Staphylococcus aureus and Bacillus subtilis) and was found similar or higher than that of free Hgati. The interaction of the complexes with calf-thymus DNA was monitored by UV?vis spectroscopy and DNA-viscosity measurements and by competitive studies with ethidium bromide; intercalation is suggested as the most possible binding mode. The interaction of the complexes with human or bovine serum albumins was studied by fluorescence emission spectroscopy and the corresponding albumin-binding constants of the complexes were calculated.
