In inorganic nomenclature, a manganate is any negatively charged molecular entity with manganese as the central atom.[1] However, the name is usually used to refer to the tetraoxidomanganate(2−) anion, MnO2− 4, also known as manganate(VI) because it contains manganese in the +6 oxidation state.[1] Manganates are the only known manganese(VI) compounds.[2]
Other manganates include hypomanganate or manganate(V), MnO3− 4, permanganate or manganate(VII), MnO− 4, and the dimanganate or dimanganate(III) Mn 2O6− 6.
A manganate(IV) anion MnO4− 4 has been prepared by radiolysis of dilute solutions of permanganate.[3][4] It is mononuclear in dilute solution, and shows a strong absorption in the ultraviolet and a weaker absorption at 650 nm.[3]
