In the title compound, C(23)H(26)O, the adamantane cage consists of three fused cyclo-hexane rings in classical chair conformations with absolute values of the C-C-C angles in the range 106.57 (11)-111.56 (12)°. The dihedral angle between the two phenyl rings is 81.38 (4)°. Although a hy-droxy group is present as a conceivable donor, no hydrogen bonds are observed in the crystal structure.
