Abstract
In the title compound, C19H22FN3OS, the dihedral angle between the inclined oxadiazole and benzene rings is 52.7 (3)degrees. In the crystal, helical supramolecular chains along [100] are sustained by N-H center dot center dot center dot S hydrogen bonds supported by methylene-benzene C-H center dot center dot center dot pi interactions. The crystal studied was an inversion twin with the fractional contribution of the minor component being 0.33 (14).
