V. Langer, J. Micová, B. Steiner and M. Koós

Abstract: In the structure of the title compound, C₁₆H₂₀O₇, the five-membered 1,3-dioxolane ring is disordered with two different positions, A and B (1/1); it adopts the ^OT₄ conformation slightly distorted towards E₄ for molecule A, and the ¹E conformation distorted towards ¹T_O for molecule B. The pyranose ring adopts an almost ideal ¹C₄ conformation. The three-dimensional packing is stabilized by strong intermolecular O-HO interactions and weak C-HO hydrogen bonds.
