The asymmetric unit of the title compound, C22H19FN2O, contains two independent molecules. The planar benzimidazole ring systems are oriented with respect to the phenyl/fluorobenzene rings at dihedral angles of 31.10(4)/45.17(5) and 45.52(5)/68.63(5)degrees, respectively, for the two molecules. In the crystal structure, intermolecular C-H center dot center dot center dot N and intermolecular C-H center dot center dot center dot N and C-H center dot center dot center dot F hydrogen bonds link the molecules into a three-dimensional network. There are C H center dot center dot center dot pi contacts between the benzimidazole and fluorobenzene rings and a pi-pi contact between the benzimidazole and phenyl ring systems [centroid-centroid distance = 4.575 (1) angstrom].
