In the title compound, C(9)H(10)N(2)O(3)·H(2)O, the Schiff base mol-ecule is approximately planar, the dihedral angle between the benzene and acetohydrazide planes being 5.40 (7)°. An intra-molecular O-H⋯O hydrogen bond is observed. In the crystal, mol-ecules are linked into a two-dimensional network parallel to (100) by O-H⋯O, N-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds, and by π-π inter-actions between symmetry-related benzene rings [centroid-centroid distance = 3.543 (2) Å].
在标题化合物C₉H₁₀N₂O₃·H₂O中，席夫碱分子近似平面，苯环与乙酰肼平面之间的二面角为5.40 (7)°。观察到分子内存在O—H⋯O氢键。在晶体中，分子通过O—H⋯O、N—H⋯O、O—H⋯N和C—H⋯O氢键以及对称相关苯环之间的π-π相互作用[质心间距 = 3.543 (2) Å]连接成平行于(100)的二维网络。
