Abstract
The molecule of the title compound, C16H17N3O2S, adopts an E conformation with respect to the azomethine C=N bond. The hydrazinecarbothioamide fragment is close to planar, with a largest deviation from the least-squares plane of 0.079 (2) Å for the hydrazide N atom. This fragment forms a dihedral angle of 9.43 (9)° with the central benzene ring. The benzene rings are inclined to one another by 67.55 (12)°. The molecular conformation is stabilized by an intramolecular O—H⋯N hydrogen bond involving the azomethine N atom. In the crystal, molecules are linked through weak N—H⋯S and N—H⋯O hydrogen bonds into double ribbons along [010]. The crystal packing also features C—H⋯π interactions.
