  2. Triiodide - Wikipedia

    en.wikipedia.org/wiki/Triiodide

    The following exergonic equilibrium gives rise to the triiodide ion: . I 2 + I − ⇌ I − 3. In this reaction, iodide is viewed as a Lewis base, and the iodine is a Lewis acid.The process is analogous to the reaction of S 8 with sodium sulfide (which forms polysulfides) except that the higher polyiodides have branched structures.

  4. Iodide - Wikipedia

    en.wikipedia.org/wiki/Iodide

    An iodide ion is the ion I −. [2] Compounds with iodine in formal oxidation state −1 are called iodides.In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate.

    However, the precise composition/structure of these chains, including the balance between molecular iodine and various iodide anions, continues to be debated and investigated, with a 2022 article suggesting that they might alternate. [9] The triiodide anion instantly produces an intense blue-black colour upon contact with starch.

    The structure of monomeric and dimeric forms have been characterized in the gas phase. [6] The monomer, AlI 3, is trigonal planar with a bond length of 2.448(6) Å, and the bridged dimer, Al 2 I 6, at 430 K is a similar to Al 2 Cl 6 and Al 2 Br 6 with Al−I bond lengths of 2.456(6) Å (terminal) and 2.670(8) Å (bridging).

  7. Polyiodide - Wikipedia

    en.wikipedia.org/wiki/Polyiodide

    The polyiodides are a class of polyhalogen anions composed entirely of iodine atoms. [1] [2] The most common member is the triiodide ion, I −3.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 ...

  9. Thallium triiodide - Wikipedia

    en.wikipedia.org/wiki/Thallium_triiodide

    Thallium triiodide is a chemical compound of thallium and iodine with formula TlI 3. Unlike the other thallium trihalides, which contain thallium(III), TlI 3 is a thallium(I) salt and contains the triiodide ion, I − 3. An appreciation as to why Tl + is not oxidised to Tl 3+ in the reaction: Tl 3+ + 2 I − → Tl + + I 2
