Synthesis, characterization and superoxide dismutase activity of some octahedral nickel(II) complexes

Four new mixed ligand nickel(II) complexes viz., [Ni(tren)(phen)](ClO4)2 (1), [Ni(tren)(bipy)](ClO4)2 (2), [Ni(SAA)(PMDT)] · 2H2O (3) and [Ni(SAA)(TPTZ)] (4) (tren = tris(2-aminoethylamine), phen = 1,10-phenanthroline, bipy = 2,2′-bipyridine, SAA = salicylidene anthranilic acid, PMDT = N,N,N′,N″,N″-pentamethyldiethylenetriamine, TPTZ = 2,4,6-tri(2-pyridyl)-1,3,5-triazine) have been synthesized and characterized by means of elemental analysis, spectroscopic, magnetic susceptibility and cyclic voltammetric measurements. Single crystal X-ray analysis of [Ni(tren)(phen)](ClO4)2 (1) and [Ni(SAA)(PMDT)] · 2H2O (3) has revealed the presence of a distorted octahedral geometry. Superoxide dismutase activity of these complexes has also been measured.

Four new octahedral Ni(II) complexes were synthesized and characterized. The crystal structures of [Ni(tren)(phen)](ClO4)2 (1) and [Ni(SAA)(PMDT)] · 2H2O (3) were determined by single crystal X-ray diffraction methods. Superoxide dismutase (SOD) activity of these complexes has also been studied.Figure optionsDownload as PowerPoint slide
