The title compound, C 18 H 28 N 6 O 6 , is a derivative of glycoluril, with two ethyl acetate substituents on the convex face of the glycoluril system. Two equivalent six-membered rings bind the N atoms from separate rings of the glycoluril unit to form the flexible sidewalls of a molecular clip. On
