title: 9,10-Diiodo-phenanthrene.
abstract: The whole mol-ecule of the title compound, C14H8I2, is generated by crystallographic twofold symmetry. The mol-ecule is planar [maximum deviation = 0.0323 (6) Å] with the I atoms displaced from the mean plane of the phenanthrene ring system by only 0.0254 (5) Å. In the crystal, mol-ecules form face-to-face slipped anti-parallel π-π stacking inter-actions along the c axis with an inter-planar distance of 3.499 (7) Å.
