Manganese carbonate is a compound with the chemical formula Mn CO 3. Manganese carbonate occurs naturally as the mineral rhodochrosite but it is typically produced industrially. It is a pale pink, water-insoluble solid. Approximately 20,000 metric tonnes were produced in 2005. [3]

Manganese(II) chlorate is an unstable chemical compound with the formula Mn(ClO 3) 2. It is unstable even in dilute solution. As a hexahydrate, it is solid below −18°C. Above this it melts, to form an extremely explosive pink liquid. [2]
[10] γ-Mn 2 O 3 is ferrimagnetic with a Néel temperature of 39 K. [14] ε-Mn 2 O 3 takes on a rhombohedral ilmenite structure (the first binary compound known to do so), wherein the manganese cations divided equally into oxidation states 2+ and 4+. ε-Mn 2 O 3 is antiferromagnetic with a Néel temperature of 210 K.

Manganese(II) acetate are chemical compounds with the formula Mn(CH 3 CO 2) 2 ·(H 2 O)n where n = 0, 2, 4. These materials are white or pale pink solids. Some of these compounds are used as a catalyst and as fertilizer. [3]
MnCO 3 → MnO + CO 2. This calcining process is conducted anaerobically, lest Mn 2 O 3 form. An alternative route, most interest for demonstration purposes, is the "oxalate method". Also applicable to the synthesis of ferrous oxide and stannous oxide, it entails heating in an oxygen-free atmosphere (often CO 2), hydrated manganese(II) oxalate: [9]
It was first reported in 1931. [2] Of the several ways to produce this compound, [3] is the protonation of the pentacarbonyl manganate anion. The latter is formed from reduction of dimanganese decacarbonyl, e.g., with superhydride: 2 LiHB(C 2 H 5) 3 + Mn 2 (CO) 10 → 2 LiMn(CO) 5 + H 2 + 2 B(C 2 H 5) 3 Li[Mn(CO) 5] + CF 3 SO 3 H → HMn(CO) 5 ...
