The title complex, [Cu(NO3)(C3H8N2S2)2]NO3, represents a low-symmetry polymorph (P-1, Z = 4) of a previously reported form [P-1, Z = 2; Ali et al. (2011 ▶). Polyhedron, 30, 542–548]. The CuII atom in each independent cation is found within a distorted square-pyramidal N2S2O coordination geometry defined by two N,S-bidentate ligands and an O atom derived from a monodentate nitrate. The primary difference between the cations is found in the relative orientations of the coordinated nitrate groups, which are directed to opposite sides of the molecule. Supramolecular layers along  and sustained by N—H⋯O interactions feature in the crystal packing. These are connected along the c axis by C—H⋯O interactions.
