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

At 160 K, the gluco­pyran­osyl ring in 1,6‐di­chloro‐1,6‐di­deoxy‐β‐d ‐fructo­furan­osyl 4‐chloro‐4‐deoxy‐α‐d ‐gluco­pyran­oside monohydrate, C₁₂H₁₉Cl₃O₈·H₂O, has a near ideal ⁴C₁ chair conformation, while the fructo­furan­osyl ring has a ⁴T₃ 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.
