title: 3-O-acetyl-4-deoxy-4-iodo-beta-D-fructofuranosyl 2,3,6-tri-o-acetyl-4-chloro-4-deoxy-alpha-D-glucopyranoside.
abstract: At 160 K, the glucopyranosyl ring of the title compound, C(20)H(28)ClIO(13), has a near-ideal (4)C(1) conformation and the fructofuranosyl ring has a twist (4)T(3) conformation. The two hydroxy groups are involved in intra- and intermolecular hydrogen bonds, with the latter interactions linking the molecules into infinite one-dimensional chains. The absolute configuration of the molecule has been determined.
