The conformation of the title compound, C27H34O, is stabilized by a weak intramolecular C—Hπ interaction. The dihedral angle between the benzene rings is 54.79 (4)°. The adamantane cage consists of three fused cyclohexane rings in classical chair conformations, with C—C—C angles in the range 107.75 (10)–111.35 (9)°. Although the molecule contains a hydroxy group as a conceivable hydrogen-bond donor, this group is sterically hindered by bulky substituents and no hydrogen bonds are observed in the crystal structure.
