Synthesis, Spectroscopic, Electrochemical and Biological studies of Schiff Base Complexes of Some 3d transition metals derived from 2-aminophenol and 2-hydroxynaphthaldehyde

Abstract

Metal chelates of Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) with Schiff base has been synthesised by the condensation of 2-aminophenol with 2-hydroxynaphthaldehyde. The ligand and it complexes are characterised by elemental analysis, molar conductance, magnetic moment, IR, 1H NMR and electronic spectral data. From the analytical and spectral data, the stiochiometry has been found to be 1:2 for all the complexes. An octahedral structure has been proposed.The Schiff base and metal complexes were screened for their antimicrobial activities on different species of pathogenic bacteria and fungi and their bio potency has been discussed.
