Abstract: The title compound, C₁₈H₁₉IN₄O₆, is a glycoluril derivative which contains four fused rings. An iodobenzene ring is fused to a seven-membered ring linked to two of the N atoms from the separate rings of the glycoluril system. The structure is stabilized by intermolecular hydrogen bonds and --stacking interactions.
