Abstract

In the title compound, {[Cu(C(7)H(8)N(4)S(4))(4)](ClO(4))(2)}(n), the Cu(II) atom, occupying a crystallographic inversion centre, is six-coordinated by six N atoms of three symmetry-related 2,2'-(propane-1,3-diyldithio)bis-(1,3,4-thia-diazole) (L) ligands in a slightly distorted octa-hedral geometry. The ligand L adopts two kinds of coordination modes in the crystal structure; one is a monodentate coordination mode and serves to complete the octa-hedral coordination of the Cu atom and the other is an N:N'-bidentate bridging mode in a trans configuration, bridging Cu atoms via translation symmetry along the b axis into a chain structure. The perchlorate ions serve as acceptors for inter-molecular C-H⋯O hydrogen bonds, which link the chains into a three-dimensional network.
