The triiodide anion is easily polarised and in many salts, one I−I bond becomes shorter than the other. Only in combination with large cations, e.g. a quaternary ammonium such as [N(CH 3) 4] +, may the triiodide remain roughly symmetrical. [3] In solution phase, the bond lengths and angles of triiodide vary depending on the nature of solvent ...
Figure 2: A donor-acceptor interaction diagram illustrating construction of the triiodide anion σ natural bond orbitals from I 2 and I − fragments. In the natural bond orbital viewpoint of 3c–4e bonding, the triiodide anion is constructed from the combination of the diiodine (I 2) σ molecular orbitals and an iodide (I −) lone pair.
Antimony triiodide is the chemical compound with the formula Sb I 3. This ruby-red solid is the only characterized "binary" iodide of antimony, i.e. the sole compound isolated with the formula Sb x I y. It contains antimony in its +3 oxidation state. Like many iodides of the heavier main group elements, its structure depends
At the cellular level, T 3 is the body's more active and potent thyroid hormone. [2] T 3 helps deliver oxygen and energy to all of the body's cells, its effects on target tissues being roughly four times more potent than those of T 4. [2] Of the thyroid hormone that is produced, just about 20% is T 3, whereas 80% is produced as T 4.
Rubidium triiodide is an orthorhombic black crystal, isomorphic to caesium triiodide, with space group Pnma, unit cell parameters a = 1090.8 pm, b = 665.5 pm, c = 971.1 pm. [2] Upon heating to 270 °C, the rubidium triiodide decomposes into rubidium iodide and elemental iodine. [1] It is soluble in ethanol and decomposes in ether. [1]

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 ...
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
