Abstract: In the molecule of the title compound, C₂₅H₁₆N₄, 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, intermolecular N-HN hydrogen bonds link the molecules into centrosymmetric dimers, forming R₂²(16) ring motifs. - 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 interactions are also present.
