The molecular and crystal structure of 2‐oxo‐1‐pyrrolidine‐acetamide

C 6 H 10 N 2 O 2 , P 1 , a = 6,607(2) Å, b = 8,538(2) Å, c = 6,392(2) Å, α = 102,43(2)°, β = 91,11(2)°, y = 79,82(2)°, V = 349,1 Å 3 , Z = 2, D m = 1,36 g × cm −3 , D x = 1,35 g × × cm −3 , MoKα radiation, λ = 1.71069 Å, μ(MoKα) = 1.11 cm −1 . The structure was solved by direct methods. The parameters were refined by full matrix least squares technique to a final R = 0.088 for 834 reflections with ∥ F 0 ∥ > 4σ( F 0 ). The dihedral angle between the least‐squares plane through the pyrrolidine ring and that through the acetamide group is 90.4°. The NH … O hydrogen bonds connect molecules to form bands parallel to the z axis.
