Preparation

Anhydrous manganese(III) oxide is found as the mineral braunite, Mn2O3, while a hydrated form, Mn2O3.H2O, which is chemically more reactive, occurs as manganite. Manganese forms both anions and cations in oxidation state +3. Simple salts of tervalent manganese are not stable. However, complexes are more stable, the hexacyanomanganates(III) being an example: K3Mn(CN)6 is a red crystalline solid, isomorphous with potassium hexacyanoferrate(III) and slowly hydrolysed.
Manganese(III) oxide is formed as a grey solid by heating manganese(IV) oxide to 700°C for several hours:
4MnO2 ---> 2Mn203 + O2
It is converted into trimanganese tetroxide when heated above 940°C in air or reduced by hydrogen above 230°C. Hot concentrated hydrochloric acid is oxidized to chlorine by manganese(III) oxide:
Mn203 (s) + 6H + + 2e- ==2Mn2+ + 3H2O
Mn203 (s) + 6H + + 2Cl- ---> 2Mn2+ + 3H2O + Cl2
