The title compound, C(14)H(11)N(3)O(4), was prepared by the reaction of 4-nitro-benzohydrazide with 4-hy-droxy-benz-alde-hyde. The whole mol-ecule of the compound is approximately planar, with a mean deviation from the least-squares plane through all the non-H atoms of 0.050 (2) Å; the dihedral angle between the two benzene rings is 2.0 (2)°. In the crystal, the benzohydrazide mol-ecules are linked through inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, forming layers in the bc plane.
标题化合物C(14)H(11)N(3)O(4)是由4-硝基苯甲酰肼与4-羟基苯甲醛反应制备的。该化合物的整个分子近似平面状，所有非H原子的最小二乘平面的平均偏差为0.050 (2) Å；两个苯环之间的二面角为2.0 (2)°。在晶体中，苯甲酰肼分子通过分子间的O-H⋯O和N-H⋯O氢键相连，在bc平面上形成层状结构。
