چکیده
In the title compound, C(15)H(14)F(2)N(2)O(3), the dihedral angle between the benzene rings is 64.5 (1)°. One F atom is disordered over two meta positions, with occupancy factors of 0.72 and 0.28. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds involving two N-H and one C=O groups of the urea central fragment, leading to a supra-molecular chain along [011].

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.

In the title amide, C(16)H(15)F(2)NO(3), the dihedral angle between the benzene rings is 53.7 (1)°. Mol-ecules are linked in the crystal structure by an inter-molecular N-H⋯O hydrogen bond involving N-H and C=O functionalities of the amide group. A one-dimensional network is thus formed along the [001] direction. No significant inter-chain contacts are observed.
