Abstract

The crystal and molecular structure of 2-sulfamino-2-deoxy-α- d-glucopyranose has been determined by direct methods. The crystal belongs to the space group P2 12 12 1 and has unit cell dimensions a=7.713 A ̊ , b=9.390 A ̊ and c= 17.222 A ̊ . The sugar ring has the expected conformation ( 4C 1) and the geometry of the N-sulfate moiety is comparable with that found in previous investigations of monosaccharide O-sulfates. The sodium ion is octahedrally coordinated involving one ring oxygen, two hydroxyls, one sulfate oxygen and two water oxygens.
