What is The crystal structure of 1,2,3,4,6-penta-O-benzoyl-α-d-mannopyranose: observation of CH⋯π interaction as a surrogate to OH⋯O interaction of a free sugar about?

The crystal structure of the title compound was determined by X-ray crystallography. The compound crystallized in the orthorhombic space group P 2 1 2 1 2 1 with four molecules in the unit cell with a 0/9.170(2), b 0/9.873 (2), c 0/38.831(8) A ̊. The structure was refined to a R index of 0.041 for 7907 independent reflections. The mannopyranose unit adopts a distorted 4 C 1 conformation. The structure depicts unique network of C Ã/HÁ Á Áp interactions, very closely resembling the pattern of O Ã/HÁ Á ÁO interactions 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.
