'''Manganese(II) nitrate''' is an ] with ] ](])<sub>2</sub>. Each ] is composed of one Mn<sup>2+</sup> ] and two ] ]s and varying amounts of water.

Manganese(II) nitrate is prepared from ] and ]:<ref name=Ullmann/> |

: {{chem2|MnO2 + 2 NO2 + 4 H2O -> Mn(H2O)4(NO3)2}} |
|
|
|
|
|
|
In this ] reaction, two ] of the ] {{chem2|NO2}} (gas) donate each one ] to {{chem2|MnO2}} (black solid), the ], which is reduced from its ] (IV) to its lower state (II). Simultaneously, {{chem2|NO2}} (IV) is oxidized to form ] ({{chem2|NO3-}}) (V). |
|
|
|
|
|
Heating the tetrahydrate to 110 °C gives the pale yellow monohydrate.<ref>{{cite journal |doi=10.1107/S056774087700689X|title=The Crystal Structure of Manganese Nitrate Monohydrate|year=1977|last1=Milinski|first1=N.|last2=Ribár|first2=B.|last3=Ćulum|first3=Ž.|last4=Djurić|first4=S.|journal=Acta Crystallographica Section B: Structural Crystallography and Crystal Chemistry|volume=33|issue=6|pages=1678–1682}}</ref> |

The reaction is reversible in the sense that heating the Mn(II) dinitrate to 450{{nbsp}}°C gives a slightly ] Mn(IV) dioxide.<ref>{{cite book|author1= Lux H.|chapter=Manganeses(II) Oxide|title=Handbook of Preparative Inorganic Chemistry, 2nd Ed. |editor= Brauer G.|publisher=Academic Press|year=1963|place=New York|volume=2|pages=1455}}</ref> |
