University, Rewa-486 003, Madhya Pradesh, India E-mail : rnp64@ymail.com Fax : 91-7662-230819 Manuscript received 19 October 2010, revised 30 May 2011, accepted 20 June 2011 A series of nickel(II) complexes [Ni(L)(L1)] (1), [Ni(L)(PMDT)] (2) and [Ni(L)(Dien)) (3) have been synthesized with newly synthesized Schifr base derived from 5-bromosalicylaldehydc and 2-aminothiophenol. L = (4-bn;mo-2- {[(2-sulfanylphenyl)imino)methyl} phenol), PMDT = N,N,N' ,N' ,N" -pentamethyldiethylenetriamine. Dien = diethylenetriamine, L1 = N-[(1)-pyridin-2-ylmethylidene]benzohydrazide. The elemental analysis of the complexes were confined to the stoichiometry of the type [M(L)(A)]. In view of analytical, spectroscopic and magnetic studies. it has been concluded that the nickel(ll) complexes possess octahedral (1-3) geometry. The redox behavior of the complexes, investigated with the aid of cyclic voltammetry, indicated the two-electron transfer process. The antimicrobial activitics of Schiff base and the complexes against E. coli were studied by the minimum inhibitory concentration method revealed that the Schiff bases and some of their metal complexes possess antibacterial activity.
