MnHCOOH2O

MnHCOOH2O, more commonly known as manganese(II) formate monohydrate, is an inorganic chemical compound. It is a salt formed from the divalent manganese cation (Mn^2+) and the formate anion (HCOO^-), with one molecule of water of hydration. The chemical formula indicates one manganese atom, one molecule of formic acid from which the formate ion is derived, and one molecule of water.

This compound typically appears as a crystalline solid, often white or pale pink in color, depending on purity and sample conditions. It is soluble in water, a characteristic common to many formate salts. The presence of the water molecule in its structure is indicated by the "2O" part of the formula, signifying a monohydrate.

Manganese(II) formate monohydrate can be synthesized through various chemical reactions, often involving the reaction of a manganese(II) salt, such as manganese(II) sulfate or manganese(II) chloride, with formic acid or a soluble formate salt under appropriate conditions. Careful control of temperature and concentration is usually required to obtain the desired crystalline product.

While not as widely used as some other manganese compounds, it finds applications in specific areas of chemistry and materials science. It can serve as a precursor for the synthesis of other manganese-containing materials or as a catalyst in certain organic reactions. Its properties are influenced by the presence of the manganese ion, which exhibits paramagnetic behavior.
