(1SR,2RS,5RS,6SR,8RS)-7,7-dimethyl- tricyclo[6.2.1.01,6]undecane-2,5,6-triol:: a supramolecular framework built from O-H ••• O hydrogen bonds

In the title compound, C13H22O3, the asymmetric unit has two independent molecules linked by a strong O-H...O hydrogen bond. The cyclohexane ring is trans fused to the cyclopentane ring bridged through an ethyl moiety. The hydroxyl groups act as donors as well as acceptors, resulting in an extensive two-dimensional hydrogen-bonded network in the (011) plane. Intermolecular O-H...O bonds between centrosymmetrically related molecules form a four-membered supramolecular assembly, leading to infinite chains parallel to the [01 (1) over bar] direction, crosslinked in the [100] direction.
