This element is often found in catalysts bound to a di-imine ligand formed by condensing ethylenediamine with salicylaldehyde. It's not osmium, but an oxide of this element bishydroxylates double bonds in cold water. It is reduced to its green plus-6 oxidation state in basic solution, its plus-4 oxidation state in neutral solution which then precipitates as a brown oxide, and its light pink plus-2 oxidation state in acid. In addition to being found chelated to that aforementioned "salen" ligand, this metal is often in its plus-7 oxidation state in an oxidizing anion with charge transfer bands that produce a strong color. For 10 points, name this metal found in that dark purple anion bound to four oxygen atoms commonly used as a redox titrant, with symbol Mn.
