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

The title compound, C13H12N2OS, 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 angstrom) and the mean plane is oriented at dihedral angles of 24.47 (11) and 28.86 (13)degrees, respectively, to the phenyl and thiophene rings. The thiophene and phenyl rings make a dihedral angle of 53.21 (8)degrees. 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 center dot center dot center dot O hydrogen bonds and weak C-H center dot center dot center dot O interactions are present in the crystal structure: three such bonds occur to the same O-atom acceptor.
