(E)-2-(2,3-Dimethyl-anilino)-N'-(thio-phen-2-yl-methyl-idene)benzohydrazide

Abstract

In the title compound, C(20)H(19)N(3)OS, the central benzene ring makes dihedral angles of 45.36 (9) and 55.33 (9)° with the thio-phene ring and the dimethyl-substituted benzene ring, respectively. The dihedral angle between the thio-phene ring and dimethyl-substituted benzene ring is 83.60 (9)°. The thio-phene ring and the benzene ring are twisted from the mean plane of the C(=O)-N-N=C bridge [maximum deviation = 0.0860 (13) Å], with dihedral angles of 23.86 (9) and 24.77 (8)°, respectively. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds to the same acceptor atom, forming sheets lying parallel to the bc plane. The crystal packing also features C-H⋯π inter-actions.
