Abstract
The crystal structure of the title compound has been determined using three dimensional X-ray diffraction data. The structure was solved by direct methods. The positional and anisotropic thermal parameters were refined using a full matrix least squares procedure to give an R factor of 0·097 for 1926 reflections. Standard deviations were ±0·004 Å in the bond lengths and ±0·2° in the bond angles. The geometry of the molecule is compared with that of other monosaccharide structures and the effect of the 3,6-anhydro-bridge is discussed. Crystal data: orthorhombic space group P212121, Z= 4, a= 9·46 ± 0·01, b= 12·05 ± 0·01, c= 6·93 ± 0·015 Å.Keywords
