Manganese(II) nitrate is an inorganic compound with formula Mn(NO3)2. Each formula unit is composed of one Mn2+ cation and two NO3 anions and varying amounts of water. Most common is the tetrahydrate Mn(NO3)2·4H2O, but mono- and hexahydrates are also known as well as the anhydrous compound. Some of these compounds are useful precursors to the oxides of manganese.[1]

Preparation[edit]

Manganese(II) nitrate can be prepared by dissolving manganese(II) carbonate in dilute nitric acid:

MnCO3 + 2 HNO3 → Mn(NO3)2 + H2O + CO2

It can also be prepared from MnO2 and nitrogen dioxide.[1]

Properties[edit]

On heating to 300°C, aqueous solutions of manganese(II) nitrate thermally decompose to form MnO2 and NO2 as products. Upon further heating, the MnO2 loses oxygen to form Mn2O3 and eventually Mn3O4.
