Benzyl 2-methyl-3-[(E)-(thio-phen-2-yl)methyl-idene]dithio-carbazate
Abstract:
In the title compound, C(14)H(14)N(2)S(3), the thione S atom and methyl group are syn, as are the two thio-ether S atoms. The mol-ecule is twisted, the dihedral angles between the central (C(2)N(2)S(2)) residue and the pendent 2-thienyl and phenyl rings being 21.57 (6) and 77.54 (3)°, respectively. In the crystal, mol-ecules assemble into a three-dimensional architecture via C-H⋯π inter-actions, involving both the five- and six-membered rings as acceptors, as well as S⋯S inter-actions [3.3406 (5) Å] between centrosymmetrically related 2-thienyl rings.
