Manganese(II) acetate are chemical compounds with the formula Mn(CH
3CO
2)
2 · (H
2O)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]
Preparation
Manganese(II) acetate can be formed by treating either manganese(II,III) oxide or manganese(II) carbonate with acetic acid:[4]
- Mn
3O
4 + 2 CH
3CO
2H → Mn(CH
