Abstract:
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
