Abstract: The asymmetric unit of the title compound, C₁₁H₁₁N₃S₂·0.5CH₄O, contains four thiosemicarbazone molecules and two methanol solvent molecules. Each hydrazinecarbothioamide molecule adopts an E configuration with respect to the C=N double bond and is stabilized by an intramolecular N-HN hydrogen bond, resulting in an S(5) ring motif. In the crystal structure, an extensive network of N-HO, N-HN, O-HS and N-HS hydrogen bonds and weak C-HO, C-HN and C-HS contacts together with an SS [3.5958 (14) Å] and a C-H interaction form a three-dimensional network.
