catena-Poly[[bis[1-(2-hydroxyethyl)-1H-tetrazole-κN4]copper(II)]-di-μ-chlorido]: a powder study

Abstract

The crystal structure of the title polymeric complex, [CuCl2(C3H6N4O)2]n, was obtained by the Rietveld refinement from laboratory X-ray powder diffraction data collected at room temperature. The unique CuII ion lies on an inversion center and is in a slightly distorted octahedral coordination environment. In the hydroxyethyl group, all H atoms, the O atom and its attached C atom are disordered over two positions; the site occupancy factors are ca 0.6 and 0.4. The OH group is involved in an intramolecular O—H...N hydrogen bond.
