ABSTRACT: In the title compound, C(29)H(19)F(2)NO(2), the central benzene ring forms a dihedral angle of 56.92?(12)° with the cyano-benzene ring and dihedral angles of 40.91?(12) and 44.76?(12)° with the two fluoro-benzene rings. In the crystal, C-H?O and C-H?F hydrogen bonds link the mol-ecules into sheets lying parallel to the ab plane. The crystal packing also features C-H?? inter-actions involving the central benzene ring.
