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, reactions, usesManganese(II) nitrate is prepared by dissolving manganese(II) oxide in nitric acid: MnO + 2 HNO3 → Mn(NO3)2 + H2O It can also be prepared from manganese dioxide and nitrogen dioxide:[1] MnO2 + 2 NO2 → Mn(NO3)2 On heating to 300 °C, aqueous solutions of manganese(II) nitrate thermally decompose to form MnO2 and NO2. Manganese(II) nitrate is the precursor to manganese carbonate, which is used in fertilizers and as a colorant. The advantage of this method, use of ammonia and carbon dioxide, being that the side product ammonium nitrate is also useful as a fertilizer.[1] References1. ^1 2 Arno H.
