C-H...N and C-H...pi interactions in 2-ethoxy-4,6-diphenylpyridine-3-carbonitrile.

The title compound, C(20)H(16)N(2)O, has two molecules in the asymmetric unit and the crystal structure shows that the central pyridine ring of each molecule has a flat boat conformation. The terminal C atom in one of the molecules is disordered over two positions, with relative occupancies of 0.594 (14) and 0.398 (14). Intermolecular C-H.N and C-H.pi interactions and pi-pi stacking, along with intramolecular C-H.N and C-H.pi interactions, help to stabilize the structure.
