Abstract

The bimetallic complexes of Co(II), Cd(II) and Hg(II) were synthesized with Schiff base ligand N, N', - Bis (Benzylidene)-1, 2 – Phenylenediamine (BENDAMB 1,2) The structural aspects of these transition metal complexes were determined by elemental analysis, molar conductance, magnetic moment measurements, 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 newly synthesized bimetallic complexes have been screened for their antimicrobial and antifungal activities. and was compared with solvent and Schiff base, screening results indicates that the metal complexes are moderately active compared with those of pure Schiff base, ligand (BENDAMB 1,2).

Keywords: Schiff base, Bimetallic, Antimicrobial activity.
