In the title mol-ecule, C(18)H(18)F(2)N(2)O(2)S, the two benzene rings, which are oriented in opposite directions with respect to the rigid 2,5-diaza-bicyclo-[2.2.1]heptane core, form a dihedral angle of 17.2 (1)°. Weak inter-molecular C-H⋯O, C-H⋯F and C-H⋯N contacts consolidate the crystal packing.
