Abstract: In the crystal structure of the title compound, C₁₄H₁₃N₃S₂, the planar phenyl and thiophene rings are bridged by a pyrazoline ring. The phenyl group is almost perpendicular to the pyrazoline ring. The pyrazoline ring adopts an envelope conformation, and the two N atoms are involved in an intramolecular N-HN(pyrazoline) and an intermolecular N-HS hydrogen bond. The average C-N bond length is 1.385 (4) Å. The crystal structure is stabilized by intra- and intermolecular hydrogen bonds and C-H stacking interactions.
