Abstract: In the title compound, [Cu(NO₃)₂(C₆H₆N₄S₄)]_n, the Cu^II atom, occupying a crystallographic inversion centre, is six-coordinated by two N atoms of two 2,2'-[1,2-ethanediylbis(thio)]bis[1,3,4-thiadiazole] ligands in trans positions, and four O atoms from two symmetry-related opposite nitrate anions, which are asymmetrically bonded, resulting in a strong distorted octahedral geometry of the central atom. The ethane group is equally disordered over two sites via another inversion centre. The bridging bidentate 2,2'-[1,2-ethanediylbis(thio)]bis[1,3,4-thiadiazole] ligands link the Cu^II centres into a one-dimensional chain. The chains are interconnected via intermolecular SO interactions [3.044 (4) and 3.084 (5) Å] and weak C-HO hydrogen bonds, generating a three-dimensional supramolecular structure.
