The molecule of the title compound, C~20~H~34~O~4~, is centrosymmetric. In the crystal structure, a network of O—H...O hydrogen bonds result in each molecule being linked to four neighbouring molecules and a two-dimensional net is formed.
The molecule of the title compound, C~15~H~26~Cl~2~, is built up from two fused six-membered and seven-membered rings. The six-membered ring has a perfect chair conformation, whereas the seven-membered ring displays a twist-chair conformation. A weak C—H...Cl hydrogen-bonding interaction links the m
