In the title compound, C(20)H(18)N(4)O(2), the dihedral angles between the central benzene ring and the pyridine rings are 57.55 (6) and 22.05 (8)°. The mol-ecular conformation is stabilized by intra-molecular N-H⋯N inter-actions and in the crystal structure an inter-molecular asymmetric cyclic hydrogen-bonding association involving both amide N-H donors and a common amide O-atom acceptor gives a chain extending along the c axis.
在标题化合物C₂₀H₁₈N₄O₂中，中心苯环与吡啶环之间的二面角分别为57.55 (6)°和22.05 (8)°。分子构象通过分子内N—H⋯N相互作用得以稳定，在晶体结构中，涉及酰胺N—H供体和一个共同酰胺O原子受体的分子间不对称环状氢键缔合形成了沿c轴延伸的链。
