✦ Synopsis

The main residue of the title compound, C 18 H 22 N 6 O 6 ÁC 2 H 4 Cl 2 , is a derivative of glycoluril. The six-membered heterocycle adopts a chair conformation and shares two N atoms with two five-membered rings of the glycoluril unit to form the flexible sidewalls of a molecular clip. Two ethyl fragments and the solvent molecule are disordered; the site occupancy factors for the ethyl groups are 0.72/0.28 and 0.75/0.25 and for the solvent molecule 0.54/0.46. Intermolecular N-HÁ Á ÁO and N-HÁ Á ÁN hydrogen bonds link the cyclopenta[cd]indene molecules into two-dimensional layers parallel to the bc plane.

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
