The Crystal and Molecular Structure of Maltitol

The crystal structure of maltitol, 4-O- -D-glucopyranosyl-D-glucitol, has been determined by X-ray diffraction method. The crystal is orthorhombic with cell parameters of a = 8.170(1), b = 12.731(1), c = 13.679(3) , space group and z = 4. The structure was solved by direct methods and refined to R = 0.030 for 1181 observed reflections measured on a diffractometer. The -glucose ring has chair conformation. The carbon atom chain of the glucitol residue has the bent, ap, Psc, Psc conformation. The angle at the ring oxygen atom is and the one at the glucosidic oxygen is . The molecules are linked by very complicated hydrogen bonds, and there is an intramolecular hydrogen bond between O(1') and O(2').
