1-Deoxy-1-fluoro-l-galactitol

Abstract

The crystal structure unequivocally confirms the relative stereochemistry of the title compound, C6H13FO5 [6-de-oxy-6-fluoro-d-galactitol or (2S,3R,4R,5S)-6-fluoro-hexane-1,2,3,4,5- penta-ol]. The absolute stereochemistry was determined from the use of d-galactose as the starting material. In the crystal, the molecules are linked by O - H⋯O and O - H⋯F hydrogen bonds, forming a three-dimensional network with each mol-ecule acting as a donor and acceptor for five hydrogen bonds.
