title: 4,4'-Diiodo-2,2'-[(3aR,7aR)-2,3,3a,4,5,6,7,7a-octa-hydro-1H-1,3-benzimidazole-1,3-di-yl)bis-(methyl-ene)]diphenol.
abstract: In the crystal structure of the title compound, C(21)H(24)I(2)N(2)O(2), the two N atoms of the imidazolidine moiety are linked to the hy-droxy groups by intra-molecular O-H⋯N hydrogen-bonding inter-actions. The cyclo-hexane ring adopts a chair conformation and the heterocyclic ring to which it is fused has a twisted envelope conformation.
