Abstract: In the title compound, C6H9N3O3, the 3-diazo-2-oxopropanamide section of the molecule is nearly planar, with a maximum deviation of 0.025 (1) Å from the mean plane of its constituent atoms. The diazo C=N=N angle is 178.0 (3)°. In the crystal, pairs of intermolecular O-HO and N-HO hydrogen bonds link the molecules into infinite double chains along the  direction. The double chains are additionally stabilized by weak C-HO contacts with CO distances of 3.039 (3) Å. Neighboring double chains in turn interact with each other through - stacking interactions [centroid-centroid distance of the 3-diazo-2-oxopropanamide units = 3.66 (6) Å] to form infinite stacks along the b axis. Molecules from neighboring stacks interdigitate with each other in the c-axis direction, thus leading to an interwoven three-dimensional network held together by O-HO, N-HO and C-HO interactions and - stacking.
