Abstract

This paper aims on Characterization and antimicrobial activities of some transition metal complexes with their heterocyclic ligands. It is better to elucidate structure of a new compound based on the experimental evidence or observation (eg IR, NMR etc) than predicting it based on the proposed reaction mechanism. The mechanism may or may not be exact route or the predicted product may or may not be the only final product predicted. Many heterocyclic ligands show good antimicrobial activities and these activities increase very much when they form complexes with metal. This shows that antimicrobial activities of metal complexes depend more on the metal center itself in addition to the structure of ligands and on the geometry around the metal ion.
