The title compound, C(10)H(8)N(4)O(4)·H(2)O, was obtained by the reaction of 5-hy-droxy-2-nitro-benzaldehyde with cyano-acetohydrazide in methanol. The non-H atoms of the hydrazone molecule are approximately coplanar, with a mean deviation from the least-squares plane of 0.056 Å. In the crystal, mol-ecules are linked by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, generating a three-dimensional network.
标题化合物C(10)H(8)N(4)O(4)·H(2)O是通过5-羟基-2-硝基苯甲醛与氰基乙酰肼在甲醇中反应得到的。腙分子的非H原子近似共面，与最小二乘平面的平均偏差为0.056 Å。在晶体中，分子通过N-H⋯O、O-H⋯N和O-H⋯O氢键相连，形成三维网络。
