Just a “reducing” sugar —namely, D ‐mannose—is a starting material in the synthesis of a mixed‐valence complex of manganese in the oxidation states + III and + IV . Ba 2 [Mn III Mn IV ( β ‐ D ‐Man f H −5 ) 2 ]Cl⋅14 H 2 O (Man f =mannofuranose; the structure of the anion is shown on the right) is prepared in aqueous solution by oxidation of an analogous Mn 2 III complex with oxygen. In neutral solutions the Mn III Mn IV binuclear complex is formed by disproportionation of the Mn 2 III precursor.
