Crystal structure of 4-amino-3-(thio­phen-3-ylmeth­yl)-1H-1,2,4-triazole-5(4H)-thione

In the title compound, C(7)H(8)N(4)S(2), the thio­phene ring shows rotational disorder over two orientations in a 0.6957 (15):0.3043 (15) ratio. The plane of the 1,2,4-triazole ring makes a dihedral angle of 75.02 (17)° with the major-disorder component of the thiophene ring. In the crystal, two types of inversion dimers, described by the graph-set motifs R (2) (2)(8) and R (2) (2)(10), are formed by N—H⋯S inter­actions. Chains of mol­ecules running in the [101] direction are linked by weaker N—H⋯N inter­actions. The thio­phene ring is involved in π–π and C—H⋯π inter­actions.
