Methyl 6-azido-6-deoxy-α-d-galactoside

The structure of the title compound, C7H13N3O5, was solved using data from a multiple fragment crystal. The galactoside ring adopts a 4C1 chair conformation. In the crystal, the molecules are linked by strong O—H...O hydrogen bonds, which build linkages around the screw axis of the cell in a similar way to the iodo analogue. These C-5 and C-6 packing motifs expand to R22(10), C22(7) and C222(8) motifs, as found in closely related compounds.
