摘要

The title compound, C21H23IN4O8, is a glycoluril derivative with five fused rings. An iodobenzene ring is fused to a seven-membered ring which binds two of the N atoms from separate rings of the glycoluril system. The other N atoms are linked via methylene groups to form an eight-membered ring with two ether O atoms separated by an additional methylene group. The crystal structure is stabilized by inversion-related C-H center dot center dot center dot pi interactions together with C-H center dot center dot center dot O non-classical hydrogen bonds.
