In the mol-ecule of the title compound, C(25)H(16)N(4), the pyridine rings are oriented at a dihedral angle of 0.92 (3)°, while the dihedral angle between the benzene ring and the adjacent pyridine ring is 56.51 (3)°. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers, forming R(2) (2)(16) ring motifs. π-π contacts between the pyridine ring and the indole ring system and between the pyridine rings [centroid-centroid distances = 3.923 (2) and 3.724 (2) Å] may further stabilize the structure. Two weak C-H⋯π inter-actions are also present.
在标题化合物C(25)H(16)N(4)的分子中，吡啶环之间的二面角为0.92 (3)°，而苯环与相邻吡啶环之间的二面角为56.51 (3)°。在晶体结构中，分子间的N-H⋯N氢键将分子连接成中心对称的二聚体，形成R(2) (2)(16)环基序。吡啶环与吲哚环系统之间以及吡啶环之间的π-π接触[质心-质心距离 = 3.923 (2) 和3.724 (2) Å]可能进一步稳定该结构。还存在两种弱的C-H⋯π相互作用。
