(E)-2-(4-Benzyloxy-2-hydroxybenzylidene)- N-phenylhydrazinecarbothioamide

The title compound, C21H19N3O2S, exists in the thione form. The configuration about the C N bond is E. The hydrazinecarbothioamide unit adopts an almost planar arrangement, with maximum deviations of 0.016 (3) and 0.016 (2) A ° for the two thiourea N atoms. An intramolecular O—H N hydrogen bond occurs. Weak intermolecular N— H S, C—H O and C—H interactions are observed in the crystal structure
