In the title compound, C29H19F3N2, the tetracyclic ring system is essentially planar [maximum deviation from the best plane = 0.076 (1) Å] and makes dihedral angles of 78.10 (5) and 33.71 (4)° with the methylphenyl and fluorophenyl rings, respectively. An intramolecular C-H interaction occurs. In the crystal, pairs of C-H interactions link inversion-related molecules.
