Manganese(II) oxide that the Mn ions form a face centered cubic magnetic sub-lattice where there are ferromagnetically coupled sheets that are anti-parallel with adjacent sheets. Manganese(II) oxide undergoes the chemical reactions typical of an ionic oxide. Upon treatment with acids, it converts to the corresponding manganese(II) salt and water. Oxidation of manganese(II) oxide gives manganese(III) oxide. MnO occurs in nature as the rare mineral manganosite. Commercially it is prepared by reduction of MnO with hydrogen, carbon monoxide or methane, e.g.: MnO can also be prepared by decarbonation of the carbonate: This calcining process is conducted anaerobically, lest MnO form.

Manganese(III) acetate Manganese(III) acetate Manganese(III) acetate describes a family of coordination complexes with the approximate formula Mn(OCCH). All are brown solids, which are soluble in acetic acid and water. These compounds are used in organic synthesis as oxidizing agents. Compounds with the formula Mn(OCCH) have not been verified. Instead manganese(III) acetate adopts the structure reminiscent of those of basic chromium acetate and basic iron acetate. For this reason, manganese(III) acetate is sometimes referred to as basic manganese acetate. The formula is [MnO(OCCH)L]X where L is a ligand and X is an anion. The coordination polymer [MnO(OCCH)]OCCHHOCCH has been crystallized. It is usually
