In the title compound, C(16)H(18)N(4)O(2), the two carbonyl groups are in an anti-periplanar conformation with an O=C-C=O torsion angle of 173.86 (17)°. In the crystal, a pair of inter-molecular N-H⋯O hydrogen bonds, forming an R(2) (2)(10) ring motif, connect the mol-ecules into an inversion dimer. The dimers are further linked by N-H⋯N and C-H⋯π inter-actions, forming a zigzag chain along the b axis.
在标题化合物C₁₆H₁₈N₄O₂中,两个羰基处于反式共平面构象,O = C - C = O扭转角为173.86 (17)°。在晶体中,一对分子间的N - H⋯O氢键形成R₂²(10)环 motif,将分子连接成一个反演二聚体。二聚体通过N - H⋯N和C - H⋯π相互作用进一步连接,沿b轴形成之字形链。
