The crystal and molecular structure of the title compound has been determined by direct methods from diffractometer data. Crystals are orthorhombic, with Z=4 in a unit cell of dimensions : a=3.811 (10), b=5.095(5), c=12.914(10) Å, space group P212121. The structure was refined by least-squares to R 3.31% for 868 observed reflections. There is significant non-planarity of the peptide group and its nitrogen atom is significantly pyramidal. There is no correlation between the double-bond character and reactivity of the C-N bond of the terminal amide group in glutamine and acetamide.
