Abstract: In the title racemic compound, C₉H₁₉O₅P, all interatomic C-C and C-OH distances can be considered normal. The P-O and P=O distances are 1.5583 (8) and 1.5003 (7) Å, respectively. The rings are cis-fused, the phospholane ring exists in a slightly distorted envelope conformation and the cyclohexane ring adopts an almost ideal chair conformation. All hydroxyl groups are anti to the P=O bond. Molecules are linked via medium-strength intermolecular O-HO hydrogen bonds into a three-dimensional network.
