Abstract

A new series of the bimetallic complexes of Ni(II), Cd(II) and Hg(II) of Schiff base ligand N, N', - Bis (Benzylidene)-1, 3 – Phenylenediamine (BENDAMB 1,3) have been synthesized these were characterized by elemental analysis, molar conductance, magnetic moment measurements and by IR, Electronic and 1H NMR spectral studies. The softness parameter TEn of complexes have also been calculated to derive the binding side of the thiocyanate ligand. The softness parameter suggest monomeric bridged structure for these complexes, magnetic susceptibility measurements indicate square planar geometry around Nickel ion. Newly synthesized bimetallic complexes have been evaluated for their antimicrobial and antifungal activities and was compared with solvent, screening results indicates that the metal complexes are moderately active compared to solvents.

Keywords: Schiff base, Bimetallic, Softness Parameter, Antimicrobial activity.
