title: {6-[2,5-Bis(chloro-meth-yl)-3,4-dihydroxy-tetra-hydro-furan-2-yl-oxy]-3-chloro-4,5-dihydr-oxy-3,4,5,6-tetra-hydro-2H-pyran-2-yl}methyl acetate dihydrate.
abstract: The title compound, C(14)H(21)Cl(3)O(9)·2H(2)O, is a disaccharide constructed from a galactose and a fructose. In the mol-ecular structure, the tetra-hydro-furan five-membered ring and tetra-hydro-pyran six-membered ring assume envelope and chair conformations, respectively. An extensive O-H⋯O hydrogen-bonding network occurs in the crystal structure.
