6-(1H-Indol-3-yl)-4-phenyl-2,2′-bi­pyridine-5-carbonitrile

In the mol­ecule 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, inter­molecular N—H⋯N hydrogen bonds link the mol­ecules 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 inter­actions are also present.
