Mixed diamine [Cu(NN)(NN)]Br2 complexes and their potential against several types of bacteria

Abstract

Mixed-diamine ligands copper(II) complexes, [Cu(NN)(NN)]Br2 (1–2) have been synthesized. These complexes were characterized by spectroscopic and thermal techniques as seen in Scheme 1. Crystal structures for seveal type of such complexes showed a distorted trigonal–bipyramidal geometry around Cu(II) ion with one solvate water molecule [1]. Antimicrobial assays were conducted to evaluate the biological activities of these complexes. The complexes showed higher antibacterial activity against several types of bacteria depending on their structures geometry.
