Diethyl 2,6-bis(4-methylbenzyl)-4,8-dioxo-2,3,6,7-tetrahydro-1H,5H-2,3a, 4a,6,7a, 8a-hexaazacyclopenta[def]fluorene-8b, 8c-dicarboxylate

The title compound, C30H36N6O6, is a glycoluril derivative with two ethyl acetate substituents on the convex face of the glycouril system. Two equivalent six-membered triazine rings bind the N atoms from separate rings of the glycouril unit to form the flexible sidewalls of a molecular clip. One N atom from each ring caries a 4-methylbenzyl substituent. The crystal structure is stabilized by intermolecular C-H center dot center dot center dot O interactions.
