Abstract
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)degrees [48.5 (4)degrees for the minor component], respectively. An intramolecular C-H center dot center dot center dot S hydrogen bond stabilizes the molecular conformation of the planar molecule. In the crystal, the two molecules are interconnected by N-H center dot center dot center dot S hydrogen bonds into dimers, which are further consolidated into chains along the b axis by C-H center dot center dot center dot N hydrogen bonds. Weak C-H center dot center dot center dot pi and pi-pi interactions [centroid-centroid distance = 3.5149 (7) angstrom] are also observed.
