Synthesis, Characterization and Biological Studies of Bimetallic Complexes Containing Co(II), Cd(II) and Hg(II) and {N, N’,-Bis (Benzylidene)-1,3,-Diamine} Schiff Base in 1:2 Ratio

A new series of bimetallic complexes Co(II), Cd(II) and Hg(II) with Schiff base ligand (N,N',-Bis(Benzylidene)-1,3-Phenylenediamine, {BENDAMB (1,3)} have been synthesized characterized by elemental analysis, molar conductance, magnetic moment measurements, IR, Electronic 1H NMR spectral studies. The softness parameter TEn also calculated to derive the binding side thiocyanate ligand. data shows that is linked comparatively harder metal Co2+ whereas SCN present as terminal. Magnetic susceptibility measurements indicate tetrahedral geometry around Cobalt ion. parameter, suggest cationic-anionic structure for these complexes. Newly screened, their antimicrobial antifungal activities was compared solvent base, screening results indicates that, are moderately active those pure BENDAMB (1,3).
