| Summary: | The title compound, C29H38N2O6, was prepared as model for studying intramolecular hydrogen-bonding interactions. Molecules of the title compound are located on a crystallographic twofold rotation axis, which passes through the C atom linked to the two N atoms on the imidazolidine ring. The molecular structure shows the existence of two intramolecular O—H...N hydrogen-bonding interactions between the two N atoms of the imidazolidine moiety and the hydroxy groups in the aromatic rings. The crystal structure shows the strain of ring fusion in the perhydrobenzimidazole moiety according to the endocyclic bond angles and the torsion angles, which evidence a puckering of the cyclohexane ring with respect to normal tetrahedral bond angles in an ideal chair conformation. |
