Lesson plan
polyiodide
The polyiodides are a class of polyhalogen anions composed entirely of iodine atoms. The most common member is the triiodide ion, . Other known larger polyiodides include [I 4 ] 2− , [I 5 ] − , [I 6 ] 2− , [I 7 ] − , [I 8 ] 2− , [I 9 ] − , [I 10 ] 2− , [I 10 ] 4− , [I 11 ] 3− , [I 12 ] 2− , [I 13 ] 3− , [I 14 ] 4- , [I 16 ] 2− , [I 22 ] 4− , [I 26 ] 3− , [I 26 ] 4− , [I 28 ] 4− and [I 29 ] 3− . All these can be considered as formed from the interaction of the I – , I 2 , and building blocks.
