3-Methyl-4-[(E)-3-thien­ylmethyl­idene­amino]-1H-1,2,4-triazole-5(4H)-thione

The asymmetric unit of the title compound, C(8)H(8)N(4)S(2), contains two crystallographically independent mol­ecules. The thio­phene ring of one mol­ecule is disordered over two positions with refined site occupancies of 0.6375 (19) and 0.3625 (19). One mol­ecule is almost planar and the other one is twisted, the dihedral angles between the thio­phene and triazole rings being 7.28 (7) and 48.9 (2)° [48.5 (4)° for the minor component], respectively. An intra­molecular C—H⋯S hydrogen bond stabilizes the mol­ecular conformation of the planar molecule. In the crystal, the two mol­ecules are inter­connected by N—H⋯S hydrogen bonds into dimers, which are further consolidated into chains along the b axis by C—H⋯N hydrogen bonds. Weak C–H⋯π and π–π inter­actions [centroid–centroid distance = 3.5149 (7) Å] are also observed.
