Bifunctional tetradentate Schiff bases of o-vanillin and 2-hydroxy-1-naphthaldehyde with ethylenediamine and their complexes of cobalt (II), nickel (II) as well as copper (II) have been synthesized. Schiff base ligands and their metal complexes have been characterized by elemental analysis, molecular weight determination, molar conductance measurements, and UV-Vis., IR, NMR (1H and 13C) and mass spectral studies. Compounds have been synthesized in an open vessel under microwave irradiation using a domestic microwave oven. The free ligands and their complexes have been tested in vitro against a number of microorganisms in order to assess their anti-microbial properties.
