Manganese(II) acetate is the chemical compound with the formula Mn(CH3COO)2. It is used as a desiccant, a catalyst, and as fertilizer.[2]

Reactions

Manganese(II) acetate can be formed by reacting acetic acid with either manganese(II,III) oxide or manganese(II) carbonate[2][3]:

Mn3O4 + 2CH3COOH → Mn(CH3COO)2 + Mn2O3 + H2O

If manganese(II,III) oxide is used, manganese(III) oxide is produced as a byproduct.

If the anhydrous form needs to be produced, manganese(II) nitrate can be reacted with acetic anhydride.[2]
