Synthesis, crystal structure, and antimicrobial activity of bis((2-(2-aminoethyl)imino-3-butanone oxime)copper(II) perchlorate

Abstract

<div><p>Copper(II) complex of an unsymmetrical tridentate ligand containing oxime, imine, and amine donors was synthesized with a condensation between diacetylmonoxime and ethylenediamine in the presence of copper(II) perchlorate. The complex is characterized by elemental analysis, IR, UV–vis, molar conductance, thermogravimetry, and single-crystal X-ray diffraction. The cation consists of two tridentate 2-(2-aminoethyl)imino-3-butanone oxime with coordination sphere of CuN₆ type. The geometry around copper(II) is distorted octahedral with two amine donors, two imine, and two nitrogens of the oxime. Photoluminescence reveals that the complex exhibits strong fluorescent emission in acetonitrile at room temperature. The antibacterial activity of the complex was also studied.</p></div
