Abstract: In the title compound, C29H19F3N2O, a phenanthroline-fused imidazole tetracyclic system, the fused benzene rings deviate slightly from the central ring and make dihedral angles with this ring of 3.47 (8) and 3.05 (8)°. The trifluoromethylphenyl ring is roughly coplanar with the phenanthroline-fused imidazole tetracyclic system [dihedral angle = 11.02 (6)°], while the methoxyphenyl ring is almost perpendicular [dihedral angle = 87.65 (6)°]. There are intramolecular C-H ...[pi] interactions involving the methoxyphenyl ring and the central phenanthroline ring, as well as an intermolecular C-H...[pi] interaction involving the phenanthroline ring. In addition, there is an intermolecular [pi]-[pi] interaction involving the central phenanthroline ring and the trifluoromethylphenyl ring [centroid-centroid distance = 3.685 (2) Å], as well as C-H...N interactions linking the molecules into dimers.
