    The polyiodide ions have much more complicated structures. Discrete polyiodides usually have a linear sequence of iodine atoms and iodide ions, and are described in terms of association between I 2, I − and [I 3] − units, which reflects the origin of the polyiodide. In the solid states, the polyiodides can interact with each other to form ...
