The structure analysis of the compound [(H3O)(18-Krone-6)]I7has been repeated. The al- ready known structure could now be described with improved precision. The unique polyiodide chain⬁1[(IÐ.2I2).I2] may be derived from the regu- lar three dimensional iodide-iodine lattice ⬁1[IÐ

.3I2] by separation.
