In the title compound, C18H13F2NO5S2, the complete molecule is generated by a crystallographic inversion centre, and the O atom and the N—H group attached to the central ring are statistically disordered. The dihedral angle between the central and terminal benzene rings is 64.03 (6)°. In the crystal, N—H...O, C—H...F and C—H...O interactions link the molecules into a three-dimensional network.
