The title compound, C(10)H(13)N(5)O(6), exhibits a highly polarized molecular-electronic structure and the conformation is influenced by two intramolecular N-H.O hydrogen bonds. The molecules are linked into a single framework by hydrogen bonds of types O-H.O [O-H = 1.22, H.O = 1.38, O.O = 2.558 (6) A and O-H.O = 160 degrees ], N-H.O [H.O = 2.26, N.O = 2.866 (6) A and N-H.O = 126 degrees ] and O-H.N [O-H = 1.26, H.N = 1.56, O.N = 2.811 (6) A and O-H.N = 170 degrees ]. The substructure generated by the O-H.O and N-H.O hydrogen bonds takes the form of a double helix.
