Abstract

The transition metal complexes of metals ions such as V(V), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Zr(IV) and Ru(III) have been synthesized from N,N’-Bis-(4-methylbenzylidene)-benzene-1,2-diamine. They have been characterized by elemental analyses, molar conductance, magnetic susceptibility, FT-IR, electronic spectra, NMR spectra, GC-MS and thermal studies. The electrochemical behaviour of metal complexes have been studied by cyclic voltammetry. The antimicrobial activity of the ligand and its metal complexes have been carried out on the bacteria Bacillus cereus, Escherichia coli, Pseudomonas aeureginosa and Staphylococcus aureus and fungi Aspergillus flavus, Aspergillus niger, Candida albicans and Penicillium by disc diffusion method.
