The asymmetric unit of the crystal structure of the title compound, C23H19F3N2O, contains two independent molecules. In the two molecules the planar benzimidazole ring systems are oriented with respect to the phenyl/trifluoromethylbenzene rings at dihedral angles of 9.62 (6)/78.63 (7) and 2.53 (8)/83.83 (9)degrees. In the crystal structure, intermolecular C-H center dot center dot center dot N hydrogen bonds link the molecules into R-2(2)(6) dimers. The molecules are elongated along [001] and stacked along the b axis.
