“…The coordination geometrical parameters (reported in tables 2 and s1)a r ev i rtually comparable in 1-3 and have typical values for this type of complexes. 14 The present data agree with those of previous structures reported of nickel(II) complexes of 1,3bis(2-pyridylmethylthio)-propane (L ′ ). 12,13 However, this more flexible ligand induces some difference in the coordination geometry dictated by the chelating requirements.…”

“…3 In particular, complexes of nickel(II) ion with nitrogen based heterocyclic ligands have been widely investigated for their potential applications in bioinorganic chemistry, 4 medicine, 5 catalysis 6,7 and great variety of biological activities as antimalarial, antibacterial, antitumoral, antiviral agents, etc. 8,9 Pursuing our continuing interest in nitrogen-sulphur polydentate chelators [10][11][12][13][14] and considering the importance of the coordination chemistry of nitrogensulfur donor ligands towards nickel ion, herein, we report an account of coordination chemistry of nickel(II) ion with a N 2 S 2 donor site (L = 3,4-bis * For correspondence (2-pyridylmethylthio)toluene) and chloride or different pseudohalide anions. The binding interaction of these complexes with calf thymus-DNA (CT-DNA), bovine serum albumin (BSA) and human serum albumin (HSA) have been studied systematically to explore the mode of biological activity which is also a part of our interest.…”

A series of neutral hexacoordinated nickel(II) complexes of formula [NiII(L)X2] (where L = 3,4-bis(2-pyridylmethylthio)toluene with tetradentate N2S2 donor set and X = chloride (1), azide (2), cyanate (3) and isothiocyanate anion (4)) have been synthesized and isolated in pure form. The complexes were characterized by physicochemical and spectroscopic methods along with detailed structural characterization of 1,2 and 3 by single crystal X-ray diffraction analyses. The structural study showed that the nickel(II) ion has a distorted octahedral geometry being chelated by the tetradentate N2S2 ligand and bound to cis- located choride or pseudohalide anions. In dimethylformamide solution the complexes showed quasi-reversible NiII/NiIII redox\ud couples in cyclic voltammograms with E1/2 values of +0.723, +0.749, +0.768 and +0.868 V for 1, 2, 3 and 4, respectively. The study of interaction of the complexes with calf thymus DNA, bovine serum albumin (BSA) and human serum albumin (HSA) using spectroscopic and physicochemical tools clearly indicates that the complexes interact with DNA via groove binding mode

Synthesis of amylopectin‐graft‐poly[(N,N‐dimethylacrylamide)‐co‐(acrylic acid)] was carried out using solution polymerization technique with potassium persulfate as the initiator. The graft copolymer was characterized by measuring molecular weight using size exclusion chromatography, thermal analysis and Fourier transform infrared (FTIR) spectroscopy. The synthetic graft copolymer was used for the removal of some potentially toxic metal ions, Cu(II), Zn(II) and Ni(II), from their aqueous solutions. Various operating parameters like the amount of adsorbent, solution pH, contact time and temperature were studied. The adsorption data were well described by the pseudo‐second‐order and Langmuir isotherm models. Metal complexation studies were carried out experimentally using cyclic voltammetry and UV‐visible and FTIR spectroscopies. The metal complex structure was also studied theoretically using density functional theory with the Gaussian 09 program and the geometry of the complex structure was optimized. The metal complexation ability of the graft polymer was in the order Cu(II) > Ni(II) > Zn(II). Calculation of the various thermodynamic parameters was also done. The negative value of free energy change indicates the spontaneous nature of the adsorption. © 2015 Society of Chemical Industry

“…The absorption spectra of BSA in the absence and presence of complexes 1 and 2 were studied at different concentrations. We observed that absorption of BSA increases frequently upon increasing the concentration of the complex, indicating the formation of a ground state complex [19,20]. As dynamic quenching does not affect the absorption spectrum of quenching molecule, the observed changes in presence of complex could be indicating static quenching interaction between complex and serum albumin.…”

The synthesis of square planar Ni(II) and Pd(II) complexes with pyrrolidine dithiocarbamate (PDTC) was characterized by elemental, physiochemical, and spectroscopic methods. Two complexes were prepared by the reaction of nickel acetate and palladium acetate with pyrrolidine dithiocarbamate (PDTC) in 1 : 2 molar ratio. The bovine serum albumin (BSA) interaction with complexes was examined by absorption and fluorescence spectroscopic techniques at pH 7.4. All the spectral data suggest that coordination of the pyrrolidine dithiocarbamate (PDTC) takes place through the two sulphur atoms in a symmetrical bidentate fashion. All the synthesized compounds were screened for their antimicrobial activity against some species of pathogenic bacteria (Escherichia coli, Vibrio cholerae, Streptococcus pneumonia, and Bacillus cereus). It has been observed that complexes have higher activity than the free ligand.
