Crystal structure of β-d,l-allose

The title compound, C(6)H(12)O(6), 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 (4) C (1) ((1) C (4)) conformation in the crystal. In the crystal, molecules are linked by O—H⋯O hyd...

Sumario:The title compound, C(6)H(12)O(6), 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 (4) C (1) ((1) C (4)) 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) Å(3), which is about 10 Å(3) smaller than that of chiral β-d-allose [V = 751.0 (2) Å(3)].
