In the title compound, C12H11N3O2S, the pyridine ring is inclined to the thiophene ring, forming a dihedral angle of 34.96 (7)°. The mean plane through the hydrazide unit forms dihedral angles of 21.57 (8) and 53.08 (8)°, respectively, with the pyridine and thiophene rings. The two O atoms are twisted away from each other, as indicated by the C—N—N—C torsion angle of −81.27 (15)°. In the crystal structure, molecules are linked into an extended three-dimensional network by intermolecular N—H...N, N—H...O and C—H...O hydrogen bonds. The crystal structure also features a short S...O [3.2686 (10) Å] interaction and a weak intermolecular C—H...π interaction.
