Methyl 6-azido-6-de-oxy-α-d-galactoside.

The structure of the title compound, C(7)H(13)N(3)O(5), was solved using data from a multiple fragment crystal. The galactoside ring adopts a (4)C(1) 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 R(2) (2)(10), C(2) (2)(7) and C(2) (2) (2)(8) motifs, as found in closely related compounds.
