Abstract

The crystal structure of the title compound was determined by X-ray crystallography. The compound crystallized in the orthorhombic space group $P2_12_12_1$ with four molecules in the unit cell with a=9.170(2), b=9.873 (2), c=38.831(8) Å. The structure was refined to a R index of 0.041 for 7907 independent reflections. The mannopyranose unit adopts a distorted $^4C_1$ conformation. The structure depicts unique network of C---H...\pi interactions, very closely resembling the pattern of O---H...Ointeractions in free sugars. This intriguing and rare observation points to a notion that the supramolecular organization pertaining to a sugar is in-built in the pyranose ring itself.
