In the title compound, C14H13N3O2S, the dihedral angle between the thiophene and phenyl rings is 24.95 (8)°. The molecular structure is consolidated by intramolecular N—HO and C—HS interactions. The crystal structure features N—HN and N—HO hydrogen bonds forming centrosymmetric R22(12) dimers, which are linked into a two-dimensional network parallel to (011) with an S(6)R22S(6) motif. In addition, π–π stacking interactions [centroid–centroid distance = 3.7013 (12) Å] occur between the thiophene and phenyl rings of adjacent molecules.

In the title compound, C12H7N3OS, the five-membered 1,3-thiazolidine ring is nearly planar [maximum deviation = 0.032 (2) Å] and makes a dihedral angle of 84.14 (9)° with the phenyl ring. In the crystal, molecules are linked by C—HN hydrogen bonds into infinite chains along [-101]. C—Hπ interactions contribute to the arrangement of the molecules into layers parallel to (101).

In the title compound, C6H4N4S3, the 1,3,4-thiadiazole ring is essentially planar, with an r.m.s. deviation of 0.001 Å. The two N—C—S—C torsion angles in the molecule are −23.41 (15) and 0.62 (14)°. One acetonitrile group is above the plane of the 1,3,4-thiadiazole ring and the other is below it, indicating syn and anti orientations. In the crystal, C—HN hydrogen bonds link the molecules into ribbons along [010].
