چکیده
In the title compound, C16H11FN4S, the dihedral angles between the triazole ring and the phenyl and fluoro-benzene rings are 23.22 (17) and 18.06 (17)°, respectively. The six-membered heterocyclic ring adopts a distorted envelope conformation, with the methyl-ene C atom as the flap. In the crystal, the mol-ecules are linked by two C-H⋯N and C-H⋯F inter-actions along [010], forming C(5), C(8) and C(13) chains repectively. C-H⋯π inter-actions involving the phenyl ring and π-π inter-actions [centroid-centroid separation for triazole rings = 3.5660 (18) Å] are also observed.
