In the title compound, C26H22ClFO2, the cyclo-propane ring is disordered over two orientations, with site-occupancy factors of 0.64 (2) and 0.36 (2). The major occupancy component of the cyclo-propane ring makes dihedral angles of 47.6 (7), 50.4 (7) and 65.4 (7)° with the fluoro-, chloro- and unsubstituted benzene rings, respectively [the corresponding values for the minor occupancy component are 47.6 (12), 51.0 (12) and 60.9 (12)°]. An intra-molecular C-H⋯O hydrogen bond occurs. The F and Cl atoms deviate by 0.0508 (12) and 0.0592 (7) Å from the planes of their attached benzene rings. In the crystal, C-H⋯F hydrogen bonds link the mol-ecules into chains along the b-axis direction.
