✦ Synopsis

The title compound, C~20~H~18~N~4~O~2~, is a molecular clip based on the glycoluril framework. The two benzene rings are each fused to a seven-membered ring; these rings bind four of the N atoms from separate rings of the glycoluril system to form the sidewalls of the molecular clip. The crystal packing is stabilized by non-classical C—H...O hydrogen bonds. There are no π–π stacking interactions in the crystal structure. The molecule provides a model with approximate non-crystallographic C
~2__v__~ symmetry.
