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

In the title compound, C17H12F2N4S, the five-membered triazole ring and two benzene rings are planar, while the six-membered thia­diazo­le ring is slightly distorted, with a mean deviation of 0.234 A. Both the ring S and adjacent non-bridgehead C atom deviate significantly [0.320 (2) and 0.370 (2) A] from the thia­diazo­le plane. In the crystal structure, four different kinds of intra- and intermolecular C—H⋯N hydrogen-bonding interactions are observed, leading to the formation of a one-dimensional zigzag chain along the crystallographic b axis.
