3-Ethyl-5,5-diphenylimidazolidine-2,4-dione

Abstract

In the title molecule, C17H16N2O2, the phenyl rings attached at the 5-position of the imidazolidine-2,4-dione ring are inclined to the five-membered ring by 60.03 (5) and 63.04 (5)°. In the crystal, N—H...O and C—H...O hydrogen bonds form chains along the a-axis direction, which are connected in pairs by additional C—H...O hydrogen bonds. The chains are tied together by C—H...π(ring) interactions.
