【 摘 要 】

The title compound, C6H12O6, a C-3 position epimer of glucose, was crystallized from an equimolar mixture of d- and l-allose. It was confirmed that d-allose (l-allose) formed β-pyran­ose with a 4C1 (1C4) conformation in the crystal. In the crystal, molecules are linked by O—H⋯O hydrogen bond, forming a three-dimensional framework. The cell volume of the racemic β-d,l-allose is 739.36 (3) Å3, which is about 10 Å3 smaller than that of chiral β-d-allose [V = 751.0 (2) Å3].
