In the title compound, C28H24F2N2O6S, the whole molecule is disordered over two sites with refined occupancies of 0.778 (3) and 0.222 (3). The central benzene ring makes dihedral angles of 56.0 (4), 34.5 (4) and 70.9 (4)°, respectively, with the two terminal benzene rings and the 1,3,4-oxadiazole ring in the major component of the disordered molecule. The corresponding angles in the minor component are 59.7 (16), 25.6 (13) and 75.5 (14)°. In the crystal, molecules are linked via C-HF, C-HN, C-HO and C-HS hydrogen bonds into a three-dimensional network. In addition, C-H interactions are observed.
