title: 2,3,3',6-Tetra-O-acetyl-4,1',6'-trichloro-4,1',4',6'-tetradeoxygalactosucrose.
abstract: At 160 K, one of the Cl atoms in the furanoid moiety of 3-O-acetyl-1,6-dichloro-1,4,6-trideoxy-beta-D-fructofuranosyl 2,3,6-tri-O-acetyl-4-chloro-4-deoxy-alpha-D-galactopyranoside, C(20)H(27)Cl(3)O(11), is disordered over two orientations, which differ by a rotation of about 107 degrees about the parent C-C bond. The conformation of the core of the molecule is very similar to that of 3-O-acetyl-1,4,6-trichloro-1,4,6-trideoxy-beta-D-tagatofuranosyl 2,3,6-tri-O-acetyl-4-chloro-4-deoxy-alpha-D-galactopyranoside, particularly with regard to the conformation about the glycosidic linkage.
