Abstract	A new series of bimetallic complexes of Co(II), Cd(II) and Hg(II) with Schiff base ligand (N,N',-Bis(Benzylidene)-1,3-Phenylenediamine, {BENDAMB (1,3)} have been synthesized and characterized 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 spectral data shows that the Schiff base ligand is linked with comparatively harder metal Co2+ whereas SCN present as terminal. Magnetic susceptibility measurements indicate tetrahedral geometry around Cobalt ion. The softness parameter, suggest cationic-anionic structure for these complexes. 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, BENDAMB (1,3).
