4-Chloro-2-[1-(4-ethyl-phen-yl)-4,5-diphenyl-1-imidazol-2-yl]phenol.

In the title compound, CHClNO, the 5-chloro-phenol ring and the imidazole ring are nearly coplanar, with a dihedral angle of 15.76 (9)° between them. The ethyl-phenyl ring and the two phenyl rings subtend angles of 71.09 (7), 43.95 (5) and 36.53 (9)°, respectively, with the imidazole plane. An intra-molecular O-H⋯N hydrogen bond supports the mol-ecular conformation, and an inter-molecular C-H⋯O inter-action, originating from an -phenyl H atom, stabilizes the packing arrangement. In addition, a weak C-H⋯π inter-action, also involving an -phenyl H atom, is observed.
