Abstract

The coordination complexes of Cu II, Zn II, Co II, Cd II and Ni II with new Schiff bases derived from O-, m- and p-methoxyaniline (Anisidine) with 3 Aldehydosalicylic acid have been synthesized. The Schiff bases and organometallic complexes have been characterized on the basis of elemental analysis, IR and NMR spectra. The metal complexes were coloured and stable in air, the Schiff base ligands act as dibasic tetra dentate nature and forms 1:1 complexes with the selected metal ions (Scheme A). The Schiff bases and their metal complexes have been tested for their antimicrobial behavior against various microorganisms and all complexes showed a good activity.

Keywords: Schiff base complexes, IR, NMR-spectra, dibasic 1:1 complexes, antimicrobial potential, microorganism.
