The crystal structure of diazomethyl beta-D-galactopyranosyl ketone.
The title compound (C8H12N2O6) crystallizes in the orthorhombic space group P2(1)2(1)2(1) (Z = 4), with a = 4.871(1), b = 11.136(2), c = 18.301(2) A. The structure was solved by the multi-solution technique and refined by full-matrix least-squares to a final R-index of 0.042. The compound adopts the 4C1(D) conformation. Bond lengths in the diazoacetyl group are consistent with the presence of a zwitterion.
