Data collection

R factor = 0.032; wR factor = 0.088; data-to-parameter ratio = 15.7. In the title molecule, C11H12N4S2, the dihedral angle between the triazole and benzene rings is 21.31 (5). A weak intra-molecular C—H S hydrogen bond generates an S(6) ring motif. In the crystal, pairs of N—H S hydrogen bonds form inversion dimers. In addition, – interactions are observed between the benzene rings, with a centroid–centroid separa-tion of 3.7599 (11) Å.
