Crystal structure of 2-[2-(hy­droxy­imino)-1-phenyl­propyl­idene]-N-phen­ylhydrazinecarbo­thio­amide

In the title compound, C(16)H(16)N(4)OS, an intra­molecular C—H⋯S hydrogen bond is observed. With the exception of the phenyl ring of the phenyl­propyl­idene unit, the remainder of the mol­ecule has an almost planar skeleton with an r.m.s. deviation of 0.121 (5) Å from the plane through the remaining 16 atoms. In the crystal O—H⋯N hydrogen bonds are observed between the terminal hy­droxy­imino groups, forming inverson dimers with R (2) (2)(6) graph-set motifs. Additional C—H⋯N contacts stack the dimers along [100]. While no π—π inter­actions are present, weak C—H⋯O and O—H⋯Cg inter­actions are also observed and help stabilize the crystal packing.
