(E)-2-[1-(1-Benzothio-phen-3-yl)ethyl-idene]hydrazinecarbothio-amide methanol hemisolvate

The asymmetric unit of the title compound, C11H11N3S2·0.5CH4O, contains four thio-semicarbazone mol-ecules and two methanol solvent mol-ecules. Each hydrazinecarbothio-amide mol-ecule adopts an E configuration with respect to the C=N double bond and is stabilized by an intra-molecular N - H⋯N hydrogen bond, resulting in an S(5) ring motif. In the crystal structure, an extensive network of N - H⋯O, N - H⋯N, O - H⋯S and N - H⋯S hydrogen bonds and weak C - H⋯O, C - H⋯N and C - H⋯S contacts together with an S⋯S [3.5958 (14) Å] and a C - H⋯π inter-action form a three-dimensional network.
