Crystal structure of (2E)-N-methyl-2-(2-oxo-1,2-di­hydroacenaphthylen-1-ylidene)hydrazinecarbo­thioamide

In the title compound, C(14)H(11)N(3)OS, the ace­naphthyl­ene ring system and hydrazinecarbo­thio­amide unit (=N—NH—C=S—NH–) are essentially coplanar [with maximum deviations from their mean planes of −0.009 (2) and 0.033 (2) Å, respectively], and make a dihedral angle of 1.59 (9)°. The mol­ecular conformation is stabilized by two weak intra­molecular hydrogen bonds (N—H⋯O and N—H⋯N), which generate S(6) and S(5) ring motifs. In the crystal, mol­ecules are linked by N—H⋯S hydrogen bonds, forming chains along [010]. The chains are linked via pairs of C—H⋯O hydrogen bonds, enclosing R (2) (2)(10) ring motifs, and C—H⋯π inter­actions, forming a three-dimensional framework. The absolute structure of the title compound was determined by resonant scattering.
