| Popis: | In the title compound, C4H9N2O3+·NO3−, alternatively called (1RS)-2-carbamoyl-1-carboxyethanaminium nitrate, the asymmetric unit comprises one asparaginium cation and one nitrate anion. The strongest cation–cation O—H...O hydrogen bond in the structure, together with other strong cation–cation N—H...O hydrogen bonds, generates a succession of infinite chains of R22(8) rings along the b axis. Additional cation–cation C—H...O hydrogen bonds link these chains into two-dimensional layers formed by alternating R44(24) and R42(12) rings. Connections between these layers are provided by the strong cation–anion N—H...O hydrogen bonds, as well as by one weak C—H...O interaction, thus forming a three-dimensional network. Some of the cation–anion N—H...O hydrogen bonds are bifurcated of the type D—H...(A1,A2). |
