The structure of the title compound, 1-[(2-chlorophenyl)diphenylmethyl]-1H-imidazole, C22H17ClN2, has been determined. The molecular conformation showed a weathercock-type structure and the three phenyl rings are almost perpendicular to the imidazole ring. The distances between the centres of the three phenyl rings and the centre of the imidazole ring are in the range 4.52-4.54 A.
