Manganese(II) acetate arechemical compounds with the formulaMn(CH3CO2)2·(H2O)n where n = 0, 2, 4. These materials are white or pale pink solids. Some of these compounds are used as acatalyst and asfertilizer.[3]
Manganese(II) acetate can be formed by treating eithermanganese(II,III) oxide ormanganese(II) carbonate with acetic acid:[4]
The anhydrous material and dihydrateMn(CH3CO2)2·2H2O arecoordination polymers. The dihydrate has been characterized by X-ray crystallography. Each Mn(II) center is surrounded by six oxygen centers provided byaquo ligands and acetates.
