6-(4-Fluoro­phen­yl)-3-phenyl-7H-1,2,4-tri­azolo[3,4-b][1,3,4]thia­diazine

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