The complete molecule of the title compound, C27H18F4N2O2, is generated by crystallographic twofold symmetry, with one C atom lying on the rotation axis. The dihedral angle between fluoro-substituted phenyl ring and the adjacent benzene ring is 10.37 (5)°. In the crystal, molecules are connected by N—H⋯O and C—H⋯F hydrogen bonds, resulting in supramolecular chains propagating along the c direction.
