In the title compound, C(7)H(6)N(2)O(4), an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonds then link the dimers, generating R(3) (3)(16)R(2) (1)(6) motifs. The whole mol-ecule is essentially planar, with the greatest deviation from the mean plane being 0.065 (2) Å.
在标题化合物C₇H₆N₂O₄中，分子内N—H⋯O氢键形成一个S(6)环。在晶体中，通过O—H⋯O氢键对连接的反演二聚体形成R₂²(8)环。分子间N—H⋯O和C—H⋯O氢键随后连接这些二聚体，形成R₃³(16)R₂¹(6) motif。整个分子基本呈平面状，与平均平面的最大偏差为0.065 (2) Å。
