چکیده
In the title compound, C(11)H(11)FN(4)S, the dihedral angle between the 1,2,4-triazole ring and the benzene ring is 25.04 (12)° and an intra-moleuclar C-H⋯S inter-action leads to an S(6) ring. In the crystal, inversion dimers linked by pairs of N-H⋯S hydrogen bonds generate R(2) (2)(8) loops.
