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

In the title compound, C₁₇H₁₂F₂N₄OS, the thia­diazine ring is non-planar and adopts a half-chair conformation. The crystal packing is stabilized by C—H...N, C—H...O and C—H...F inter­molecular hydrogen-bonding inter­actions.
