| Popis: | The title compound, K+·C5H11O8S− [systematic name: potassium (1R,2R,3R,4R)-1,2,3,4,5-pentahydroxypentane-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 hydroxymethyl group, form an essentially all-trans chain; the C atom of the hydroxymethyl 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 intermolecular O—H...O hydrogen bonding, a three-dimensional bonding network exists in the crystal structure. |
