Summary:The asymmetric unit of the title compound, C 18 H 18 I 2 N 2 O 2 , 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.
