α-l-Glucose.

Commercially available l-glucose, C6H12O6, was crystallized by slow evaporation from aqueous solution at room temperature affording colorless block-shaped single crystals suitable for single-crystal X-ray diffraction. The title compound crystallizes as α-l-glucose in the ortho-rhom-bic space group P212121, with one mol-ecule in the asymmetric unit and Z = 4. In the crystal, the mol-ecules are linked by O-H⋯O hydrogen bonds, forming a three-dimensional hydrogen-bonded network. This study provides an experimentally determined structural dataset for the rare l enanti-omer, which is not currently represented in the Cambridge Structural Database.
