摘要：

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)degrees with the terminal phenyl and benzene rings, respectively. The latter rings make a dihedral angle of 33.06 (13)degrees with each other. The corresponding values for molecule B are 26.86 (13), 41.82 (12) and 38.99 (13)degrees, respectively. In the crystal, the B molecules are linked via a pair of weak C-H center dot center dot center dot N hydrogen bonds, forming inversion dimers. In addition, C-H center dot center dot center dot pi interactions and pi-pi [centroidcentroid distances = 3.5056 (16) and 3.8569 (17) angstrom] stacking interactions are observed.
