The crystal and molecular structures of 2-amino-2-deoxy-a/fl-D-glucopyranose 3-sulfate (1) and 2-amino-2-deoxy-fl-D-glucopyranose 6-sulfate (2) have been determined by direct methods. The sugar rings have the expected 4C1 conformation and the geometries of the sulfate groups are comparable with thos
