2-Eth-oxy-4-(4-methyl-phen-yl)-6-phenyl-pyridine-3-carbonitrile.
The title compound, C(21)H(18)N(2)O, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. In mol-ecule 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 mol-ecule B are 26.86 (13), 41.82 (12) and 38.99 (13)°, respectively. In the crystal, the B mol-ecules are linked via a pair of weak C-H⋯N hydrogen bonds, forming inversion dimers. In addition, C-H⋯π inter-actions and π-π [centroid-centroid distances = 3.5056 (16) and 3.8569 (17) Å] stacking inter-actions are observed.
