(E)-N′-[1-(Thio­phen-2-yl)ethyl­idene]benzohydrazide

The title compound, C(13)H(12)N(2)OS, was obtained from the condensation reaction of 2-acetyl­thio­phene and benzohydrazide. In the mol­ecule, the formohydrazide fragment is approximately planar (r.m.s deviation = 0.0146 Å) and the mean plane is oriented at dihedral angles of 24.47 (11) and 28.86 (13)°, respectively, to the phenyl and thio­phene rings. The thio­phene and phenyl rings make a dihedral angle of 53.21 (8)°. The benzamide fragment and thio­phene ring are located on the opposite sides of the C=N bond, showing an E conformation. Classical inter­molecular N—H⋯O hydrogen bonds and weak C—H⋯O inter­actions are present in the crystal structure: three such bonds occur to the same O-atom acceptor.
