All the complexes were characterized by physicochemical and spectroscopic methods. An octahedral geometry has been proposed for all the complexes. The new complexes have been tested to find out their catalytic activity for the oxidation or alcohols to corresponding carbonyl compounds. Further the ligands and complexes were subjected to antimicrobial activity studies
