Polyatomic ions often are useful in the context of acid–base chemistry and in the formation of salts. Often, a polyatomic ion can be considered as the conjugate acid or base of a neutral molecule. For example, the conjugate base of sulfuric acid (H 2 SO 4) is the polyatomic hydrogen sulfate anion (HSO − 4).
Structural formula of Na 2 HPO 3.The anion has C 3v symmetry.. From the commercial perspective, the most important phosphite salt is basic lead phosphite.Many salts containing the phosphite ion have been investigated structurally, these include sodium phosphite pentahydrate (Na 2 HPO 3 ·5H 2 O).
The polyiodide ions have much more complicated structures. Discrete polyiodides usually have a linear sequence of iodine atoms and iodide ions, and are described in terms of association between I 2, I − and [I 3] − units, which reflects the origin of the polyiodide. In the solid states, the polyiodides can interact with each other to form ...
A silicate is any member of a family of polyatomic anions consisting of silicon and oxygen, usually with the general formula [SiO (4-2x)− 4−x] n, where 0 ≤ x < 2. The family includes orthosilicate SiO 4− 4 (x = 0), metasilicate SiO 2− 3 (x = 1), and pyrosilicate Si 2 O 6− 7 (x = 0.5, n = 2).

Sulfur forms several polyatomic molecules. The best-known allotrope is octasulfur, cyclo-S 8. The point group of cyclo-S 8 is D 4d and its dipole moment is 0 D. [12] Octasulfur is a soft, bright-yellow solid that is odorless. [a] It melts at 115.21 °C (239.38 °F), [b] and boils at 444.6 °C (832.3 °F). [8]
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 ...
