In the title compound, C(9)H(10)N(2)O(2)·H(2)O, the mol-ecular skeleton of the acetohydrazide mol-ecule is nearly planar [within 0.014 (1) Å]. The mol-ecule adopts a trans configuration with respect to the C=N bond, while the side chain is slightly twisted away from the attached ring, forming a dihedral angle of 9.975 (8)°. The crystal packing exhibits a three-dimensional network composed from alternating acetohydrazide mol-ecules and uncoordinated water mol-ecules, which inter-act via N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds. A C-H⋯π inter-action is also present.
在标题化合物C₉H₁₀N₂O₂·H₂O中，乙酰肼分子的分子骨架近乎平面（偏差在0.014 (1) Å范围内）。分子相对于C=N键采取反式构型，而侧链略微偏离所连接的环扭转，形成9.975 (8)°的二面角。晶体堆积呈现出由交替的乙酰肼分子和未配位的水分子组成的三维网络，它们通过N—H⋯O、O—H⋯O和O—H⋯N氢键相互作用。还存在C—H⋯π相互作用。
