title: Crystal structure of N-(tri-O-acetyl-alpha-D-xylopyranosyl)pyridinium bromide.
abstract: The structure of N-(2,3,4-tri-O-acetyl-alpha-D-xylopyranosyl)pyridinium bromide was determined by X-ray crystallography and 1H NMR spectroscopy. Two xylopyranosyl moieties crystallize with three water molecules and there is a novel pattern of Br(-) and H(2)O contacts. Both xylopyranosyl rings in the asymmetric unit have the 1C(4) conformation, with all three axial O-Ac groups.
