(2 E )-2-[(4-Ethoxyphenyl)imino]-1,2-diphenylethanone

The title compound, C 22 H 19 NO 2 , is an imino-ketone Schiff base. The configuration about the azomethine bond is E . The aromatic rings of the 1,2-diphenylethanone moiety are inclined to each other by 80.43 (7)°. The 4-ethoxyphenyl ring is inclined to the phenylethanone ring by 81.91 (7)° and to the phenyl ring to which it is trans by 68.56 (7)°. In the crystal, four symmetry-related molecules are linked by C—H...O hydrogen bonds to form square-like units with an R 3 4 (36) ring motif, which are linked through bifurcated C—H...O hydrogen bonds to form sheets parallel to the (10 1 ) plane.
