Coordination properties of 1,3-benzothiazoles. Formation of a polymeric complex with square-planar coordination around the copper(II) ion in the reaction of CuCl2·6H2O with 1,2-bis[2-(1,3-benzo-thiazol-2-yl)phenylthio]ethane

Abstract

It is shown that a coordination polymer is formed by the reaction of 1,2-bis[2-(1,3-benzothiazol-2-yl)-phenylthio]ethane with copper(II) chloride in a mixture of ethanol and chloroform at room temperature. The structure of the polymer has been determined by X-ray crystallography. The copper atom in the coordination polymer has a square-planar ligand environment and is coordinated to the nitrogen atoms of the benzothiazole rings of two different molecules of ligand and two chloride anions.
