1-Phenyl-2-[4-(trifluoromethyl)phenyl]-1H-benzimidazole

In the title molecule, C20H13F3N2, the benzimidazole unit is close to being planar [maximum deviation = 0.012 (1) ] and forms dihedral angles of 31.43 (7) and 61.45 (9)° with the 4-(trifluoromethyl)phenyl and 1-phenyl rings, respectively; the dihedral angle between these rings is 60.94 (10)°. In the crystal, C—H...F hydrogen bonds link the molecules into chains along the c-axis direction. The CF3 group is rotationally disordered with an occupancy ratio of 0.557 (8):0.443 (8) for the F atoms.
