The asymmetric unit of the title compound, C(23)H(17)F(3)N(2)O(2), contains two mol-ecules. In one of the mol-ecules, the phenyl and triflouromethyl-substituted benzene rings form dihedral angles of 52.05 (8) and 33.70 (8)°, respectively, with the benzimidazole ring system, while the dihedral angle between them is 58.24 (10)°. The corresponding values in the other mol-ecule are 58.40 (8), 25.90 (8) and 60.83 (10)°, respectively. In the crystal, mol-ecules are linked into chains along [100] by C-H⋯O and C-H⋯N hydrogen bonds. Aromatic π-π stacking inter-actions [centroid-centroid distance = 3.6700 (12) Å] also occur.
