Abstract: In the title molecule, C₂₀H₁₃F₃N₂, the benzimidazole unit is close to being planar [maximum deviation = 0.012 (1) Å] 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-HF 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.
