Abstract
In the title compound, C(6)H(12)O(5), the cyclo-hexane ring adopts a chair conformation. The absolute configuration is not defined. However, the relative configuration can be assigned as 1R*,3R*,4S*,S*. In the crystal structure, mol-ecules are linked by strong inter-molecular O-H⋯O hydrogen bonds, producing a three-dimensional network.Entities:

| Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
