Crystal structure of S-hexyl (E)-3-(2-hydroxybenzylidene)dithiocarbazate

The title compound, C₁₄H₂₀N₂OS₂ [systematic name: S-hexyl (E)-2-(2-hydroxybenzylidene)hydrazine-1-carbodithioate], crystallizes with four independent molecules (A-D) in the asymmetric unit. All four molecules adopt an E conformation with respect to the C=N bond of the benzylidene moiety and have an intramolecular O-H⋯N hydrogen bond generating an S(6) ring motif. In the crystal, the A and D molecules are connected by a pair N-H⋯S hydrogen bonds, forming a dimer with an R₂²(8) ring motif. In the case of molecules B and C, they are linked to themselves by pairs of N-H⋯S hydrogen bonds, forming B-B and C-C inversion dimers with R₂²(8) ring motifs.
