The absolute configuration of the title compound, C18H24O5·H2O, was not been determined by anomalous-dispersion effects, but has been assigned by reference to an unchanging chiral centre in the synthetic procedure. Intramolecular O—HO hydrogen bonds stabilize the molecular conformation. In the crystal, O—HO hydrogen bonds link the main molecules and the water molecules, forming an infinite three-dimensional network.

The asymmetric unit of the title compound, C18H26O5, which is known as α-zearalanol, contains two molecules having the same conformation, with a r.m.s. deviation of less than 0.03 Å for all non-H atoms. In each independent molecule, an intramolecular O—HO hydrogen bond stabilizes the molecular conformation. In the crystal, O—HO hydrogen bonds link the molecules, forming infinite chains along [110] and [1-10].
