Abstract: In the title compound, {[Cu(C₇H₈N₄S₄)₄](ClO₄)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-thiadiazole) (L) ligands in a slightly distorted octahedral 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 octahedral 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 intermolecular C-HO hydrogen bonds, which link the chains into a three-dimensional network.
