Molecules of the title compound, C5H6N4O3, are linked into a single three-dimensional framework by a two-centre N-H...O hydrogen bond [H...O = 1.92 Angstrom, N...O = 2.785 (2) Angstrom and N - H...O = 168 degrees], a two-centre N - H...H hydrogen bond [H...N = 2.19 Angstrom, N...N = 3.017 (2) Angstrom and N - H...N = 157 degrees] and the intermolecular component of an effectively planar three- centre N - H...(O)(2) hydrogen bond [H...O = 2.03 and 2.31 Angstrom, N...O = 2.645 (2) and 2.957 (2) Angstrom, N-H...O = 126 and 130degrees, and O...H...O = 101 degrees].
