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 [110] and sustained by N—H⋯O inter­actions feature in the crystal packing. These are connected along the c axis by C—H⋯O inter­actions.
