Polybis­(acetonitrile-κN)bis­μ2-22′-(methyl­enedithio)bis­(134-thia­diazole)-κ2 N 4:N 4′copper(II) bis­(perchlorate) acetonitrile solvate

摘要

In the title compound, {[Cu(C5H4N4S4)2(C2H3N)2](ClO4)2·C2H3N}n, the Cu^II 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.
