In the structure of the title compound, C(20)H(18)N(4)O(2), the N-H and C=O bonds are trans to each other and the amide O atoms are syn to the ortho amino N atom in the benzoyl rings. The amide groups form dihedral angles of 8.4 (2) and 13.8 (2)° with their respective benzoyl rings, and dihedral angles of 51.85 (16) and 51.19 (17)° with the phenyl-enediamine ring. In the crystal, a centrosymmetric dimer is formed by inter-molecular N-H⋯O hydrogen bonds, resulting in an R(2) (2)(14) descriptor on a unitary level of graph-set analysis, and three intramolecular N-H⋯O bonds also occur.
在标题化合物C(20)H(18)N(4)O(2)的结构中，N-H键和C=O键彼此呈反式，且酰胺O原子与苯甲酰环中的邻氨基N原子呈顺式。酰胺基团与其各自的苯甲酰环形成的二面角为8.4 (2)°和13.8 (2)°，与苯二胺环形成的二面角为51.85 (16)°和51.19 (17)°。在晶体中，通过分子间N-H⋯O氢键形成了一个中心对称二聚体，在图形集分析的单一水平上得到R(2) (2)(14)描述符，并且还存在三个分子内N-H⋯O键。
