Crystal structure of (E)-4-{1-[2-(carbamothioyl)hydrazin-1-ylidene]ethyl}-phenyl 4-methylbenzoate

The asymmetric unit of the title compound, C17H17N3O2S, consists of two independent molecules, A and B, with different conformations: in molecule A, the dihedral angles between the central benzene ring and the pendant tolyl and carbamothioylhydrazono groups are 71.12 (9) and 5.95 (8)degrees, respectively. The corresponding angles in molecule B are 50.56 (12) and 26.43 (11)degrees, respectively. Both molecules feature an intramolecular N-H center dot center dot center dot N hydrogen bond, which closes an S(5) ring. In the crystal, molecules are linked by N-H center dot center dot center dot O, NH center dot center dot center dot S and C-H center dot center dot center dot O hydrogen bonds, generating a threedimensional network.
