(E)-2-[1-(1-Benzothio-phen-3-yl)ethyl-idene]hydrazinecarbothio-amide methanol hemisolvate
Abstract:
The asymmetric unit of the title compound, C(11)H(11)N(3)S(2)·0.5CH(4)O, 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.
