Arsonium
The arsonium cation is a positively charged polyatomic ion with the chemical formula AsH+4. An arsonium salt is a salt containing either the arsonium (AsH+4) cation, such as arsonium bromide (AsH+4Br−) and arsonium iodide (AsH+4I−), which can be synthesized by reacting arsine with hydrogen bromide or hydrogen iodide. Or more commonly, as organic derivative such as the quaternary arsonium salts Ph4As+Cl− (CAS: 123334-18-9 , hydrate form) and the zwitterionic compound arsenobetaine.
