Abstract
The crystal and molecular structure of 2,7-anhydro-l-glycero-β-d-manno-octulopyranose has been determined by X-ray analysis. Crystal data area = 9.590(4),b = 7.404(5),c=7.363(4) Å, β = 101.79(3)°,Z = 2, space groupP21. The phase problem was solved by direct methods, using diffractometer data, and the structure was refined by least-squares techniques to a finalR value of 3.7%. The anhydro ring system is built up by the pyranosyl chair in the1 C 4 conformation, the five-membered ring in theE 0 conformation, and a boat-shaped seven-membered ring. Potential energy calculations show that the positions of the terminal CH2OH groups are determined by hydrogen bonds.
