Abstract
The title salt, Na+·C6H13O9S− [systematic name: sodium (1S,2S,3S,4R,5R)-1,2,3,4,5,6-hexahydroxyhexane-1-sulfonate], is formed by reaction of d-mannose with sodium bisulfite (sodium hydrogen sulfite) in water. The carbohydrate anions are arranged in a head (–SO3 −) to head (–SO3 −) arrangement, thereby forming two parallel sheets linked through coordination to sodium ions, with each component sheet containing intermolecular hydrogen bonds between the anionic residues. Unusually, the double sheets are not connected to neighbouring sets of double sheets, either by ion coordination or intermolecular hydrogen bonding.
