4,1′,6′-Trichloro-4,1′,6′-trideoxysucrose monohydrate

At 160 K, the glucopyranosyl ring in 1,6-dichloro-1,6-dideoxy-beta-D-fructofuranosyl 4-chloro-4-deoxy-alpha-D-glucopyranoside monohydrate, C(12)H(19)Cl(3)O(8).H(2)O, has a near ideal (4)C(1) chair conformation, while the fructofuranosyl ring has a (4)T(3) conformation. The conformation of the sugar molecule is quite different to that of sucralose, particularly in the conformation about the glycosidic linkage, which affects the observed pattern of intramolecular hydrogen bonds. A complex series of intermolecular hydrogen bonds links the sugar and water molecules into an infinite three-dimensional framework.
