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—HO interactions.

In the title compound, C14H14N2S3, the thione S atom and methyl group are syn, as are the two thioether S atoms. The molecule is twisted, the dihedral angles between the central (C2N2S2) residue and the pendent 2-thienyl and phenyl rings being 21.57 (6) and 77.54 (3)°, respectively. In the crystal, molecules assemble into a three-dimensional architecture via C—Hπ interactions, involving both the five- and six-membered rings as acceptors, as well as SS interactions [3.3406 (5) Å] between centrosymmetrically related 2-thienyl rings.

In the title compound, C14H14N2OS2, the furan ring exhibits rotational disorder over two orientations, with an occupancy ratio of 0.508 (7):0.492 (7). The furan and phenyl rings form dihedral angles of 8.2 (6) (major occupancy component), 14.8 (6) (minor occupancy component) and 73.65 (9)°, respectively, with the central residue (C4N2S2), indicating a twisted conformation for the molecule. The methyl group and the thione S atom are syn and the conformation about the imine bond is E. In the crystal, C—Hπ interactions involving the phenyl ring are observed.

The title compound, C4H6N2S3, has two very similar molecules per asymmetric unit. The nine non-H atoms in each molecule are coplanar, both having comparable r.m.s. deviations of 0.002 Å. The main interest in the rather simple structure resides in a survey of very weak (in some cases, borderline) non-bonding interactions of various kinds, viz. SS, C—Hπ, π–π [centroid–centroid distance = 3.8958 (13) Å] and C—Sπ [3.7271 (11) Å], which act as the major driving force for the arrangement of molecules in the structure. The role of long, though highly directional, SS contacts (d > 3.60 Å), and their relevance to the stability of the structure is discussed.
