Manganese(III) phosphate is an inorganic chemical compound of manganese with the formula MnPO 4. It is a hygroscopic purple solid that absorbs moisture to form the pale-green monohydrate, [ 1 ] though the anhydrous and monohydrate forms are typically each synthesized by separate methods.
Manganese(II) phosphate is an inorganic compound with the chemical formula Mn 3 (PO 4) 2. It has industrial importance as a constituent of manganese based phosphate conversion coatings . Formation

A general formula for such cyclic compounds is [HPO 3] x where x = number of phosphoric units in the molecule. When metaphosphoric acids lose their hydrogens as H +, cyclic anions called metaphosphates are formed. An example of a compound with such an anion is sodium hexametaphosphate (Na 6 P 6 O 18), used as a sequestrant and a food additive.
Manganese(II,III) oxide is the chemical compound with formula Mn 3 O 4. Manganese is present in two oxidation states +2 and +3 and the formula is sometimes written as MnO · Mn 2 O 3 . Mn 3 O 4 is found in nature as the mineral hausmannite .
4] 3− is derived from phosphoric acid by the removal of three protons H +. Removal of one proton gives the dihydrogen phosphate ion [H 2 PO 4] − while removal of two protons gives the hydrogen phosphate ion [HPO 4] 2−. These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.
This is similar to the relationship between γ-Fe 2 O 3 and Fe 3 O 4. [ 10 ] γ-Mn 2 O 3 is ferrimagnetic with a Néel temperature of 39 K. [ 14 ] ε-Mn 2 O 3 takes on a rhombohedral ilmenite structure (the first binary compound known to do so), wherein the manganese cations divided equally into oxidation states 2+ and 4+. ε-Mn 2 O 3 is ...
