The mol-ecule of the title compound, C(10)H(11)N(3)O(3), adopts an all-trans conformation and is approxomately planar, the largest deviation from the least-squares plane through all non-H atoms being 0.261 (1) Å. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, the mol-ecules are packed into layers lying parallel to the ab plane by π-stacking inter-actions between the benzene ring of one molecule and the C-N bond of the oxime group of another molecule; the shortest inter-molecular C⋯C separation within the layer is 3.412 (1) Å. The layers are connected by O-H⋯O and N-H⋯O hydrogen bonds.
标题化合物C(10)H(11)N(3)O(3)的分子呈全反式构象且近似平面，所有非氢原子的最小二乘平面的最大偏差为0.261 (1) Å。分子内存在O-H⋯N氢键。在晶体中，分子通过一个分子的苯环与另一个分子肟基的C-N键之间的π-堆积相互作用堆积成平行于ab平面的层；层内最短的分子间C⋯C间距为3.412 (1) Å。这些层通过O-H⋯O和N-H⋯O氢键相连。
