The asymmetric unit of the title compound, C18H18I2N2O2, consists of one half-mol­ecule, completed by the application of inversion symmetry. The mol­ecule adopts the typical structure for this class of bis-benxozazines, characterized by an anti orientation of the two benzoxazine rings around the central C—C bond. The oxazinic ring adopts a half-chair conformation. In the crystal, mol­ecules are linked by C—I⋯N short contacts [I⋯N = 3.378 (2) Å], generating layers lying parallel to the bc plane.
