At 160 K, the gluco­pyran­osyl ring of the title compound, C20H28ClIO13, has a near‐ideal 4C1 conformation and the fructo­furan­osyl ring has a twist 4T3 conformation. The two hydroxy groups are involved in intra‐ and intermolecular hydrogen bonds, with the latter interactions linking the mol­ecules...

Zusammenfassung:At 160 K, the gluco­pyran­osyl ring of the title compound, C20H28ClIO13, has a near‐ideal 4C1 conformation and the fructo­furan­osyl ring has a twist 4T3 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.
