In the title compound, C20H24N2O4, both peptide bonds adopt a trans configuration with respect to the -N-H and -C=O groups. The dihedral angle between the aromatic rings is 53.58 (4)°. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. The crystal packing is characterized by zigzag chains of N-H⋯O hydrogen-bonded mol-ecules running along the b-axis direction.
在标题化合物C₂₀H₂₄N₂O₄中,两个肽键相对于-N-H和-C=O基团均呈反式构型。芳环之间的二面角为53.58 (4)°。分子构象通过分子内N-H⋯O氢键得以稳定。晶体堆积的特征是沿b轴方向由N-H⋯O氢键连接的分子形成锯齿链。
