4,4′-Dichloro-3,3′,5,5′-tetra­methyl-2,2′-[(3aR,7aR/3aS,7aS)-2,3,3a,4,5,6,7,7a-octa­hydro-1H-1,3-benzimidazole-1,3-di­yl)bis­(methyl­ene)]diphenol

In the title compound, C(25)H(32)Cl(2)N(2)O(2), there are two intra­molecular O—H⋯ N hydrogen-bonding inter­actions between the hy­droxy groups on the aromatic rings and the two N atoms of the heterocyclic group. The cyclo­hexane ring adopts a chair conformation and the imidazolidine unit to which it is fused has a twisted envelope conformation. The asymmetric unit comprises one half-mol­ecule which is completed by a twofold rotation axis. A C—H⋯O inter­action is observed in the crystal structure.
