Triveni Chemicals

Thallium triiodide is a chemical compound of thallium and iodine with formula tli3. Unlike the other thallium trihalides, which contain thallium(iii), tli3 is a thallium(i) compound and contains the triiodide ion, i3−.

In chemistry, triiodide (sometimes written tri-iodide) can have several meanings. Triiodide primarily refers to the triiodide ion, i3−, a polyatomic anion composed of three iodine atoms. For some chemical compounds, triiodide indicates a salt of the named cation with the triiodide anion. Examples include sodium triiodide, thallium triiodide, and ammonium triiodide, [nh4][i3]. Each of these compounds has a (mono)iodide counterpart. For other chemical compounds, triiodide indicates that each molecule contains three iodine atoms that are not bonded to each other, not forming the triiodide ion.

Antimony triiodide is the chemical compound with the formula sbi3. This ruby-red solid is the only characterized "binary" iodide of antimony, i. E. The sole compound isolated with the formula sbxiy. Like many iodides of the heavier main group elements, its structure depends on the phase. Gaseous sbi3 is a molecular, pyramidal species as anticipated by vsepr theory.

Phosphorus triiodide (pi3) is an unstable red solid which reacts violently with water. It is a common misconception[1] that pi3 is too unstable to be stored; it is, in fact, commercially available. It is widely used in organic chemistry for converting alcohols to alkyl iodides.
