Abstract

Three different ortho substituted dinuclear copper(II) complexes [Cu2L(O2CC6H4-O-X)] [where X = COOH(1), NH2(2), OH(3)] were synthesized by the reaction of corresponding precursor with pentadentate Schiff base ligand. The synthesized complexes were characterized by molar conductance, UV-Vis., FTIR spectroscopic techniques. The electrochemical behaviour was investigated by Cyclic Voltammetry for the complexes. The ligand and the synthesized complexes have been screened for in vitro antibacterial activity.

Keywords: Pentadentate Schiff base, Copper (II) complexes, Cyclic voltammetry, antibacterial activity.
