1-Phenyl-2-[4-(trifluoro-meth-yl)phen-yl]-1H-benzimidazole.

ABSTRACT

In the title mol-ecule, C(20)H(13)F(3)N(2), 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-H⋯F hydrogen bonds link the mol-ecules into chains along the c-axis direction. The CF(3) group is rotationally disordered with an occupancy ratio of 0.557 (8)0.443 (8) for the F atoms.
