2-Eth­oxy-4-(4-methyl­phen­yl)-6-phenyl­pyridine-3-carbonitrile

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
