4DescriptionAbstract New bidentate ligands N1,N4-bis(2-amino-5-nitrobenzylidene)benzene-1,4-diamine, L1 and N4,N4-bis(2-amino-5-nitrobenzylidene)biphenyl-4,4'-diamine, L2 have been synthesized. The ligand L1 and L2 were treated with Cu(OCOCH3)2.H2O and Ni(OCOCH3)2.4H2O to afford the new homobi-metallic complexes [CuL1] 2.4(Oac) (1), [NiL1] 2.4(Oac) (2), [CuL2] 2.4(Oac) (3) and [NiL2] 2.4(Oac) (4) respectively. The four new homobimetallic complexes have been characterized by spectral techniques like elemental analysis, NMR, IR, UV Visible absorption, magnetic measurements, thermal, EPR, electrochemical studies and molar conductance. IR spectral data shows that the ligands are bidentate and the binding sites are azomethine nitrogen and free primary amine groups. Molar conductance measurements show that the complexes are electrolytes. EPR values and electronic spectral data suggest that it possesses square planar geometry. The Schiff base ligands and metal complexes were evaluated for antimicrobial activity against gram positive bacteria and gram negative bacteria. The ligands and its metal complexes were found to be biologically active. All the complexes show higher antimicrobial activity than the ligand and streptomycin
