In the title compound, C(17)H(15)N(3)O(4), the mol-ecule is in the keto-hydrazone form. Intra-molecular N-H⋯O hydrogen bonds ensure that the mol-ecule is nearly planar (r.m.s. deviation of non-H atoms is 0.098 Å), with the two benzene rings forming a dihedral angle of 10.04 (2)°. In the crystal, inversion dimers are formed via pairs of O-H⋯O hydrogen bonds involving the -CO(2)H groups.
在标题化合物C(17)H(15)N(3)O(4)中,分子呈酮腙形式。分子内N-H⋯O氢键确保分子近乎平面(非H原子的均方根偏差为0.098 Å),两个苯环形成的二面角为10.04 (2)°。在晶体中,通过涉及-CO(2)H基团的O-H⋯O氢键对形成了反演二聚体。
