Crystal structure of 4-[(E)-(4-fluoro­benzyl­idene)amino]-3-methyl-1H-1,2,4-triazole-5(4H)-thione

The title compound, C(10)H(9)FN(4)S, crystallizes with two mol­ecules (A and B) in the asymmetric unit. The dihedral angle between the planes of the trizole and fluoro­benzene rings is 7.3 (3)° in mol­ecule A and 41.1 (3)° in mol­ecule B. Mol­ecule A features an intra­molecular C—H⋯S hydrogen bond, which closes an S(6) ring. In the crystal, A+B dimers linked by pairs of N—H⋯S hydrogen bonds occur, generating R (2) (2)(8) loops. Weak π–π stacking contacts [centroid–centroid separation = 3.739 (6) Å] are also observed.
