In the title inclusion compound, C(26)H(26)N(4)O(6)center dot C(2)H(4)Cl(2), the solvent molecule occupies a cavity inside the clip-type molecule which is based on the glycoluril skeleton with two ethyl acetate substituents on the convex face of the glycoluril system. The dihedral angle between the aromatic rings of the host is 43.59 (4)degrees and the centroid-centroid distance is 6.741 (5) angstrom. The 1,2-dichloroetane molecule adopts a gauche conformation enabling it to participate in C-H center dot center dot center dot pi interactions with the host. The packing motif in the title compound differs from that observed in the crystal structures of the host and in the benzene solvate. The host molecules are linked into tapes by pi-pi stacking interactions (centroid-centroid distance = 3.733 angstrom) and are further assembled into layers via C-H center dot center dot center dot O interactions. One of the ethyl groups is disorded over two positions with site-occupancy factors of 0.702 (14) and 0.298 (14).
