Reactions
Manganese(II) acetate can be formed by treating either manganese(II,III) oxide or manganese(II) carbonate with acetic acid:[4]
- 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.
