چکیده
In the title compound, C15H22O2, both five-membered rings display an envelope conformation whereas the six-membered ring displays a chair conformation. In the crystal, pairs of O-H⋯O hydrogen bonds between carb-oxy-lic groups link mol-ecules, related by a twofold rotation axis, into supra-molecular dimers.
