چکیده
In the title compound, C(33)H(25)F(2)NO(2), the acenaphthene ring system forms dihedral angles of 50.93 (14) and 36.89 (14)° with the benzene rings. The pyrrolidine and cyclo-penta-none rings adopt envelope (with the N atom as the flap) and twisted conformations, respectively. In the crystal, C-H⋯O and C-H⋯F inter-actions link the mol-ecules.
