dimanganate

Dimanganate is a chemical species with the formula Mn2O7^2-. It is the dianion of dimanganic acid, H2Mn2O7. Dimanganate is an oxyanion of manganese in the +7 oxidation state. It is related to the permanganate ion, MnO4^-, and the manganate ion, MnO4^2-. Dimanganate is less common than permanganate or manganate. It can be formed under specific conditions involving manganese compounds. For example, it can be synthesized through the reaction of permanganate with certain oxidizing agents in acidic media. The structure of the dimanganate ion consists of two manganese atoms linked by an oxygen atom, with the remaining oxygen atoms coordinated to each manganese atom. The manganese atoms in dimanganate are in a very high oxidation state, which makes the ion a strong oxidizing agent. However, dimanganate is generally less stable and less frequently encountered than the permanganate ion. Its properties and reactivity are influenced by the presence of two manganese centers in close proximity. Further research on dimanganate is ongoing to fully understand its chemical behavior and potential applications.
