| Abstract: | The solid-state conformation of the title compound, C20H32N2O9, has been determined at 150 K. The pyranose ring has a distorted chair conformation. Among the possible conformations of the C—N glycosidic bond, that of the E rotamer is observed and a short intramolecular Cmethyl⋯O contact may partly stabilize this conformation. Crystal cohesion is stabilized by an extensive network of weak C—H⋯O hydrogen bonds and close contacts. |
