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—HS and N—HO hydrogen bonds into double ribbons along [010]. The crystal packing also features C—Hπ interactions.

The asymmetric unit of the title compound, C21H25N3O2S·0.5C2H3N, contains two independent molecules with almost similar structural properties along with a solvent molecule of acetonitrile. The compound exists in the E conformation with respect to the azomethine C=N double bond. The hydrazinecarbothioamide moieties in both independent molecules are almost planar [maximum deviations of 0.013 (2) and 0.007 (2) Å]. The molecular conformation is stabilized in each case by an intramolecular N—HN hydrogen bond. In the crystal, pairs of N—HS hydrogen bonds link each of the independent molecules into inversion dimers. The dimers are interconnected by means of three C—Hπ interactions.
