2-[1-(4-tert-Butyl-phen-yl)-4,5-diphenyl-1H-imid-azol-2-yl]-4,6-di-chloro-phenol.

In the title compound, C(31)H(26)Cl(2)N(2)O, the 4,6-di-chloro-phenol and the imidazole rings are almost coplanar, with a dihedral angle of 8.89†(6)° between them and an intra-molecular O-H⋯N hydrogen bond occurs between the rings. The dihedral angles subtended by the tert-butyl-phenyl ring and the two phenyl rings with the imidazole ring are 85.18†(9), 81.22†(9) and 19.00†(8)°, respectively. The methyl groups of the tert-butyl grouping are disordered over two sets of sites in 0.589†(5):0.411†(5) ratio. In the crystal, inversion dimers linked by pairs of weak C-H⋯Cl inter-actions generate R (2) (2)(24) loops.
