The title compound, CH(3)N(5)O(4), is almost planar, and the conformation is fixed by two intramolecular N-H...O hydrogen bonds. Owing to the delocalization of pi-electron density over the whole molecule, there is through-conjugation, with the C-N, N-N and N-O bond lengths having values intermediate between those typical for the corresponding single and double bonds.
