Crystal structure of potassium (1R)-d-ribit-1-yl-sulfonate.

Haines AH, Hughes DL - Acta Crystallogr Sect E Struct Rep Online (2014)

Bottom Line: The title compound, K(+)·C5H11O8S(-) [systematic name: potassium (1R,2R,3R,4R)-1,2,3,4,5-penta-hydroxy-pentane-1-sulfonate], formed by reaction of d-ribose with potassium hydrogen sulfite in water, crystallizes as colourless plates.The anion has an open-chain structure in which the S atom and the C atoms of the sugar chain, excepting that of the hy-droxy-methyl group, form an essentially all-trans chain; the C atom of the hy-droxy-methyl group lies in a gauche relationship with the three contiguous C atoms.Through complex cation coordination (through seven oxygen atoms of six different anions) and inter-molecular O-H⋯O hydrogen bonding, a three-dimensional bonding network exists in the crystal structure.
