Manganese(II) acetate

Manganese(II) acetate are chemical compounds with the formula Mn(CH3CO2)2*(H2O)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.

Preparation
Manganese(II) acetate can be formed by treating either manganese(II,III) oxide or manganese(II) carbonate with acetic acid:


 * Mn3O4 + 2 CH3CO2H → Mn(CH3CO2)2 + Mn2O3 + H2O
 * MnCO3 + 2 CH3CO2H → Mn(CH3CO2)2 + CO2 + H2O

Structure
The anhydrous material and dihydrate Mn(CH3CO2)2*2H2O are coordination polymers. The dihydrate has been characterized by X-ray crystallography. Each Mn(II) center is surrounded by six oxygen centers provided by aquo ligands and acetates.
