The title compound, C21H18N2O, crystallized with two independent molecules (A and B) in the asymmetric unit. In molecule A, the central pyridine ring forms dihedral angles of 14.55 (13) and 39.14 (12)° with the terminal phenyl and benzene rings, respectively. The latter rings make a dihedral angle of 33.06 (13)° with each other. The corresponding values for molecule B are 26.86 (13), 41.82 (12) and 38.99 (13)°, respectively. In the crystal, the B molecules are linked via a pair of weak C-H...N hydrogen bonds, forming inversion dimers. In addition, C-H...[pi] interactions and [pi]-[pi] [centroid-centroid distances = 3.5056 (16) and 3.8569 (17) Å] stacking interactions are observed.
