Abstract

Synthesis, Spectral, Cyclic Voltammetric and Antimicrobial Studies of Copper (II) Complexes with Tetradentate Bis-Benzomidazole Based Diamide Ligand

Author(s): Magan Prasad and Yogesh K. Sharma

A new tetradentate bis-benzimidazole based diamide ligand, N-butyl-N,N’-bis-(2-methylbenzimidazolyl)- benzene-1,3-dicarboxamide[B–GBBA] has been synthesized and utilized to prepare Cu (II) complexes of general composition [Cu(B-GBBA)X2].nH2O where X is an exogenous anionic ligand (X = Cl-, NO3 -). These complexes were prepared in the molar ratios of metal : ligand (1 : 1) and characterized by elemental analysis, IR, UV spectroscopic and other analytical techniques. Cyclic voltammetric measurements of the complexes display quasi reversible redox wave due to the Cu (II)/Cu (I) process. The distorted octahedral geometry with monomeric composition was proposed for both the complexes on the basis of these studies. These complexes have been screened for their antimicrobial activities against bacteria, E. coli and S.aureus and were found to exhibit considerable activity.
