Abstract:
The title compound, C8H16O6·H2O, was prepared by Fischer glycosyl-ation of d-sorbose with ethanol. Colorless block-shaped single crystals suitable for single-crystal X-ray diffraction were obtained. The title compound crystallizes in the ortho-rhom-bic space group P212121, with one sorboside mol-ecule and one water mol-ecule in the asymmetric unit. The sorboside mol-ecule adopts an α-pyran-ose form with a 5 C 2 chair conformation. In the crystal, the sorboside and water mol-ecules are linked by O-H⋯O hydrogen bonds, forming an extended hydrogen-bonded network.
