(E)-2-(4-Benz-yloxy-2-hy-droxy-benzyl-idene)-N-phenyl-hydrazinecarbothio-amide.
The title compound, C(21)H(19)N(3)O(2)S, exists in the thione form. The configuration about the C=N bond is E. The hydrazinecarbothio-amide unit adopts an almost planar arrangement, with maximum deviations of 0.016 (3) and -0.016 (2) Å for the two thio-urea N atoms. An intra-molecular O-H⋯N hydrogen bond occurs. Weak inter-molecular N-H⋯S, C-H⋯O and C-H⋯π inter-actions are observed in the crystal structure.
