Abstract: The title compound, C₂₀H₂₁IN₄O₇, is a glycoluril derivative which contains five 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, and the other two N atoms are linked to an O atom by two of the methylene groups. The structure of the compound possesses normal geometrical parameters. The crystal packing is consolidated by intermolecular hydrogen bonds, resulting in a two-dimensional network.
