Abstract
Abstract Trisodium β- d -fructose 1,6-diphosphate octahydrate crystallises in the monoclinic space group P21 with unit-cell dimensions a = 13.289(2), b = 11.643(3), c = 7.092(1) A, and β = 102.32(2)°. The unit cell contains two symmetry-related molecules. The structure has been determined by direct methods, and refined to an R value of 0.035 and an Rw value of 0.049. The puckering of the furanose ring is C-3-exo, corresponding to an E3 conformation slightly distorted towards 4T3. The sodium atoms are hexaco-ordinated. The crystal packing involves alternating charged layers and a network of hydrogen bonds which links the molecules belonging to the same layer and to adjacent layers.
