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, C16H14O4, the benzene rings are inclined at a dihedral angle of 75.14 (9)°. The torsion angle of the bridging O—C—C—O group is −76.50 (11)°. In the crystal, molecules are linked by C—HO hydrogen bonds, forming C(6) chains along [100]. Furthermore, C—Hπ interactions and π–π stacking interactions [centroid–centroid distances = 3.6957 (7) and 3.6735 (8) Å] contribute to the stability of the crystal packing.

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).
