چکیده
In the title mol-ecule, C(19)H(24)O(6), the cyclo-hexa-none ring adopts a chair conformation. The dihedral angle between the phenyl ring and the best plane through the six atoms of the cyclo-hexa-none ring is 89.68 (7)°. In the crystal structure, mol-ecules are linked via pairs of inter-molecular O-H⋯O hydrogen bonds into centrosymmetric dimers and these dimers are connected by C-H⋯O inter-actions into columns down the a axis.
