## Abstract

High resolution $^1H$ NMR and $^{13}C$ NMR spectroscopic and single crystal X-ray structural analyses of N-acetamido-3,4,6- tri-O-acetyl-2-azido-2-deoxy-$\alpha$-D-galactopyranosylamine (1), a minor product of azidonitration reaction of 3,4,6-tri-O-acetyl galactal, are reported. The solution phase studies of 1 reflect that the compound exists in $^4C_1$ conformation with cis-orientation of the substituents at C-1 and C-2. The solid-state structure of 1 reveals that a molecule of water is entrapped in the solid state of 1 and this water molecule serves to mediate $N-H\cdot\cdot\cdot{O}$ and $C-H\cdot\cdot\cdot{O}$ interactions.
