Experimental

R factor = 0.059; wR factor = 0.143; data-to-parameter ratio = 19.2. In title compound, C27H36O, all cyclohexane rings within the adamantyl groups adopt chair conformations. There are no obvious intermolecular hydrogen bonds in the structure, so that van der Waals attractions stabilize the crystal.
