(E)-N'-[1-(Thio-phen-2-yl)ethyl-idene]benzohydrazide.

ABSTRACT

The title compound, C(13)H(12)N(2)OS, was obtained from the condensation reaction of 2-acetyl-thio-phene and benzohydrazide. In the mol-ecule, 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 thio-phene rings. The thio-phene and phenyl rings make a dihedral angle of 53.21 (8)°. The benzamide fragment and thio-phene ring are located on the opposite sides of the C=N bond, showing an E conformation. Classical inter-molecular N-H⋯O hydrogen bonds and weak C-H⋯O inter-actions are present in the crystal structure three such bonds occur to the same O-atom acceptor.
