Poly[[bis(acetonitrile-κN)bis[μ2-2,2′-(methylenedithio)bis(1,3,4-thiadiazole)-κ2N4:N4′]copper(II)] bis(perchlorate) acetonitrile solvate]

Abstract

In the title compound, {[Cu(C5H4N4S4)2(C2H3N)2](ClO4)2·C2H3N}n, the CuII atom occupies a crystallographic inversion centre and is six-coordinated by six N atoms of four symmetry-related 2,2′-(methylenedithio)bis(1,3,4-thiadiazole) (L) ligands and two acetonitrile molecules in a slightly distorted octahedral geometry. The ligand L adopts an N:N′-bidentate bridging mode in a trans configuration, bridging the Cu atoms via translation symmetry, forming a two-dimensional layer-like structure. The perchlorate ions serve as acceptors for intermolecular C—H...O hydrogen bonds, which link the layers into a three-dimensional network. The ClO4− anion is disordered with an occupation ratio of 0.658:0.342.
