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
The molecule of the title compound, C 22 H 36 N 6 O 6 , exhibits normal geometric parameters. Both imidazole rings adopt envelope conformations with the C O group at the flap position. The triazinane rings adopt chair conformations.
In the title compound, C 26 H 40 N 6 O 6 , the five-membered rings adopt envelope conformations and the six-membered rings are in chair conformations. The crystal packing is stabilized by C-HÁ Á ÁO hydrogen bonds.
