| Popis: | The title compound, C6H12O6, was crystallized from an aqueous solution of equimolar mixture of d- and l-fructose (1,3,4,5,6-pentahydroxyhexan-2-one, arabino-hexulose or levulose), and it was confirmed that d-fructose (or l-fructose) formed β-pyranose with a 2C5 (or 5C2) conformation. In the crystal, two O—H...O hydrogen bonds between the hydroxy groups at the C-1 and C-3 positions, and at the C-4 and C-5 positions connect homochiral molecules into a column along the a axis. The columns are linked by other O—H...O hydrogen bonds between d- and l-fructose molecules, forming a three-dimensional network. |
