Abstract
The crystal structure of maltitol, 4-O-α -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) Å, space group P212121 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 α-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 112.6° and the one at the glucosidic oxygen is 117.1°. The molecules are linked by very complicated hydrogen bonds, and there is an intramolecular hydrogen bond between O(1') and O(2').
