Abstract: 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-HO 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.
