In the title compound, C(32)H(27)N(3)O, the fused tetra-cycilc ring system is essentially planar [r.m.s. deviation = 0.07 (7) Å]. An intra-molecular N-H⋯π(arene) inter-action and a weak intra-molecular C-H⋯N hydrogen bond may influence the mol-ecular conformation. In the crystal, weak inter-molecular C-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers, forming R(2) (2)(14) motifs. In addition, weak π-π stacking inter-actions with centroid-centroid distances in the range 3.578 (1)-3.739 (1) Å provide further stabilization.
在标题化合物C(32)H(27)N(3)O中，稠合四环体系基本呈平面状[r.m.s.偏差 = 0.07 (7) Å]。分子内N-H⋯π(芳烃)相互作用和弱分子内C-H⋯N氢键可能影响分子构象。在晶体中，弱分子间C-H⋯N氢键将分子连接成中心对称二聚体，形成R(2) (2)(14) motif。此外，质心间距在3.578 (1)-3.739 (1) Å范围内的弱π-π堆积相互作用提供了进一步的稳定性。
