In the title compound, C 29 H 19 F 3 N 2 , 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⋯π interaction occurs. In the crystal, pairs of C - H⋯π interactions link inversion-related molecules.
