1-Benzyl-2-phenyl-1H-benzimidazole–4,4′-(cyclo­hexane-1,1-di­yl)diphenol (1/1)

The asymmetric unit of the title co-crystal, C(20)H(16)N(2)·C(18)H(20)O(2), contains one mol­ecule of 4,4′-(cyclo­hexane-1,1-di­yl)diphenol (in which the cyclo­hexane ring adopts a chair conformation) and one mol­ecule of 1-benzyl-2-phenyl-1H-benzimidazole, which are paired through an O—H⋯N hydrogen bond. These pairs are further linked by inter­molecular O—H⋯O hydrogen bonds into chains along [010]. Weak inter­molecular C—H⋯O and C—H⋯π inter­actions further consolidate the crystal packing. The dihedral angles between the pendant phenyl rings and the benzimidazole ring are 86.9 (2) and 43.1 (2)°.
