Ammonium triiodide [1] [2] (NH 4 I 3) is the salt of the ammonium cation with the triiodide anion. Sometimes the name ammonium triiodide is mistakenly used to refer to a different compound, nitrogen triiodide (NI 3 ), or more precisely, the slightly more stable ammine , NI 3 · NH 3 .
In chemistry, triiodide usually refers to the triiodide ion, I − 3. This anion, one of the polyhalogen ions, is composed of three iodine atoms. It is formed by combining aqueous solutions of iodide salts and iodine. Some salts of the anion have been isolated, including thallium(I) triiodide (Tl + [I 3] −) and ammonium triiodide ([NH 4] + [I ...
Nitrogen triiodide is an inorganic compound with the formula N I 3. It is an extremely sensitive contact explosive : small quantities explode with a loud, sharp snap when touched even lightly, releasing a purple cloud of iodine vapor; it can even be detonated by alpha radiation .
The solid crystal of tetra-n-butylammonium iodide is in the monoclinic crystal system. It has space group C2/c. The unit cell has dimensions a=14.2806 b=14.1864 c=19.5951 β=111.149. There are eight formulae in the unit cell (Z=8), which has volume 3702.4 Å 3. [1]
Tetra-n-butylammonium triiodide (TBAI 3) is a quaternary ammonium salt with a triiodide counterion. It is a common carrier of the triiodide used in chemical synthesis of photovoltaic materials, [2] organic conductors and superconductors. [3] In crystals, the triiodide moieties are linear and shows high crystallinity.
The X ions are not fixed and can migrate through the crystal with an activation energy of 0.6 eV; the migration is vacancy assisted. [1] The methylammonium cations can rotate within their cages. At room temperature the ions have the CN axis aligned towards the face directions of the unit cells and the molecules randomly change to another of the ...
Ivanka Trump wore diamond jewelry with a total value of $1.1 million at Donald Trump's inauguration. She wore the jewelry with gowns designed by Oscar de la Renta and Givenchy.
Ammonium iodide is the inorganic compound with the formula NH 4 I. A white solid. It is an ionic compound, although impure samples appear yellow. This salt consists of ammonium cation and an iodide anion. [1] It can be prepared by the action of hydroiodic acid on ammonia. It is easily soluble in water, from which it crystallizes in cubes.
