The tetrafluoroammonium cation (also known as perfluoroammonium) is a positively charged polyatomic ion with chemical formula NF + 4. It is equivalent to the ammonium ion where the hydrogen atoms surrounding the central nitrogen atom have been replaced by fluorine. [1] Tetrafluoroammonium ion is isoelectronic with tetrafluoromethane CF 4 ...
The term molecule may or may not be used to refer to a polyatomic ion, depending on the definition used. The prefix poly-carries the meaning "many" in Greek, but even ions of two atoms are commonly described as polyatomic. [2] In older literature, a polyatomic ion may instead be referred to as a radical (or less commonly, as a radical group).
In chemistry, the pentazenium cation (also known as pentanitrogen) is a positively-charged polyatomic ion with the chemical formula N + 5 and structure N−N−N−N−N.Together with solid nitrogen polymers and the azide anion, it is one of only three poly-nitrogen species obtained in bulk quantities.
The phosphotungstate anion, an example of a polyoxometalate. In chemistry, a polyoxometalate (abbreviated POM) is a polyatomic ion, usually an anion, that consists of three or more transition metal oxyanions linked together by shared oxygen atoms to form closed 3-dimensional frameworks.

Zintl ions can oxidize without the presence of specific oxidizing agents through solvent molecules or impurities, for example in the presence of cryptand, which is often used to aid crystallization. [15] Zintl ion clusters can be functionalized with a variety of ligands in a similar reaction to their oligomerization. As such, functionalization ...
The best known polycation of mercury is Hg 2+ 2, in which mercury has a formal oxidation state of +1. The Hg 2+ 2 ion was perhaps the first metal-metal bonded species confirmed. The presence of the Hg 2+ 2 ion in solution was shown by Ogg in 1898. [7] In 1900, Baker showed the presence of HgCl dimers in the vapour phase. [8] The presence of Hg 2+
