In the title compound, C(26)H(20)N(6)O(4), the two aroylhydrazone side groups exist as diastereomeres, both in the keto form in the crystal structure. The aroylhydrazone units support the mol-ecular conformation through an intra-molecular N-H⋯O hydrogen bond. Two mol-ecules are connected into a centrosymmetric dimer by inter-molecular N-H⋯N hydrogen bonds. These dimers are connected into chains along the a axis by inter-molecular O-H⋯O hydrogen bonds. The combination of these hydrogen bonds results in layers in the bc plane. The layers are further linked by weak C-H⋯π contacts to form a three-dimensional network structure.
在标题化合物C₂₆H₂₀N₆O₄中，两个芳酰腙侧基以非对映异构体形式存在，在晶体结构中均为酮式。芳酰腙单元通过分子内N-H⋯O氢键支持分子构象。两个分子通过分子间N-H⋯N氢键连接成中心对称二聚体。这些二聚体通过分子间O-H⋯O氢键沿a轴连接成链。这些氢键的组合在bc平面上形成层。这些层通过弱C-H⋯π接触进一步连接形成三维网络结构。
