✦ Synopsis

The title compound, C~12~H~11~N~3~OS, was synthesized by the reaction of 2-pyridinecarbonylhydrazide with 2-acetylthiophene in ethanol. In the molecule, the dihedral angle between the pyridine and thiophene rings is 24.4 (3)°. In the crystal structure, zigzag chains are formed along the b axis by weak intermolecular C—H...N interactions. These chains are, in turn, further assembled into a two-dimensional supramolecular structure through weak intermolecular C—H...O and N—H...O hydrogen bonds.
