✦ Synopsis
In the title racemic compound, C 9 H 19 O 5 P, 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) A ˚, 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-HÁ Á ÁO hydrogen bonds into a three-dimensional network.

The two pyrrolidine rings in the title compound, C~25~H~22~N~2~O~6~, adopt envelope conformations. Molecules are stabilized by intramolecular O—H...O hydrogen bonds, and linked into centrosymmetric dimers by intermolecular N—H...O hydrogen bonds.
