In methyl β-D-fructopyran­oside, C7H14O6, the thermodynamically most stable methyl glycoside of the ketose D-fructose, the pyran­ose ring is close to being an ideal 2C5 chair. The compound forms bilayers involving a complex hydrogen-bonding pattern of five independent hydrogen bonds. Graph-set analysis was applied to distinguish the hydrogen-bond patterns at unary and higher level graph sets.
