The crystal and molecular structure of 2-(N-nitrosomethylamino)acetamide

Crystals of 2-(N-nitrosomethylamino)acetamide are monoclinic, space group P2₁/n, with a = 16.681 (30), b = 4.774 (5), c = 14.318 (15) Å and β = 92.95 (20)°. Each unit cell contains four molecules of the E isomer and four of the Z isomer. The structural model was refined to R = 0.044 for 1184 independent reflections measured using an automatic diffractometer. Hydrogen bonds from amide groups to carbonyl or nitroso oxygen atoms connect the molecules in sheets parallel to (100).
