Abstract

The complexes were synthesised using pentadentate Schiff base ligand with three different precursors by eco-friendly method and it was characterised by UV-VIS, FT-IR, ESR spectral techniques and Conductivity Measurements. The electrochemical behaviour was investigated by Cyclic Voltammetry for the complexes. The ligand and complexes were subjected to antimicrobial studies. A correlation of these data suggested that the complexes are of the type [MLR] where R= [(NH2)-C6H4COO], R= [(COOH)-C6H4COO] & R= [C6H5CH=CHCOO] are the complex-I, II & III respectively.

Keywords: Solvent less, Copper (II) precursors, Copper (II) complexes, ESR and Antimicrobial activity.
