The title compound, C(15)H(13)N(3)O(5), was prepared by condensing 5-hy-droxy-2-nitro-benzaldehyde and 2-hy-droxy-3-methyl-benzohydrazide in methanol. The two benzene rings make a dihedral angle of 3.9 (3)°. An intra-molecular O-H⋯O hydrogen bond is observed. The crystal structure is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, and C-H⋯O and π-π inter-actions [centroid-centroid distances = 3.5658 (17)-3.9287 (19) Å].
标题化合物C(15)H(13)N(3)O(5)是通过5-羟基-2-硝基苯甲醛与2-羟基-3-甲基苯甲酰肼在甲醇中缩合制备的。两个苯环形成的二面角为3.9(3)°。观察到分子内O-H⋯O氢键。晶体结构通过分子间O-H⋯O和N-H⋯O氢键以及C-H⋯O和π-π相互作用[质心-质心距离 = 3.5658(17)-3.9287(19)Å]得以稳定。
