Heating the tetrahydrate to 110 °C gives the pale yellow monohydrate. [4] The reaction is reversible in the sense that heating the Mn(II) dinitrate to 450 °C gives a slightly nonstoichiometric Mn(IV) dioxide. [5] Manganese(II) nitrate is the precursor to manganese(II) carbonate (MnCO 3), which is used in fertilizers and as a colourant.
A particularly common oxidation state for manganese in aqueous solution is +2, which has a pale pink color. Many manganese(II) compounds are known, such as the aquo complexes derived from manganese(II) sulfate (MnSO 4) and manganese(II) chloride (MnCl 2). This oxidation state is also seen in the mineral rhodochrosite (manganese(II) carbonate ...
Manganese(II) chloride is the dichloride salt of manganese, MnCl 2. This inorganic chemical exists in the anhydrous form, as well as the di hydrate (MnCl 2 ·2H 2 O) and tetrahydrate (MnCl 2 ·4H 2 O), with the tetrahydrate being the most common form.

This list includes those recognised minerals beginning with the letter E.The International Mineralogical Association is the international group that recognises new minerals and new mineral names; however, minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.

Manganese nitrides are salts of manganese and the nitride ion. Four of these compounds are stable at atmospheric pressure . The most important is Mn 3 N 2 , which catalyzes nitrogen fixation and is a high-temperature antiferromagnet .
