The title acid, C6H10O6, crystallized in the non-centrosymmetric space group I2, with half a molecule in the asymmetric unit (the molecular symmetry is 2). In the single type of hydrogen bond, the carboxylic H atom is ordered, and the OD...OA distance is 2.665 (2) A. Each molecule is linked to four others by hydrogen bonds and to two others by C-H...O interactions. The dihedral angle between intramolecular carboxyl-group planes is 85.2 (1) degree.
该标题酸，化学式为C6H10O6，结晶于非中心对称空间群I2中，不对称单元中有半个分子（分子对称性为2）。在单一类型的氢键中，羧基氢原子有序排列，OD...OA距离为2.665(2) Å。每个分子通过氢键与另外四个分子相连，并通过C-H...O相互作用与另外两个分子相连。分子内羧基平面之间的二面角为85.2(1)度。
