The molecule of the title compound, C14H8I 2, an inter-mediate in the synthesis of organic materials, is nearly planar, the maximum deviation from the mean plane being 0.032 (1) Å for the C atoms and 0.082 (2) Å for the I atoms. In the crystal structure, a sandwich-herringbone arrangement of molecules is observed, whereas a columnar π-stacking arrangement has been reported for the chlorinated congener 1,8-dichloro-anthracene. Similar effects of halogen substituents on the modulation of packing arrangements are reported for halogenated aromatic compounds such as tetra-cenes and chrycenes.
