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

The last one is pyrophosphate [P 2 O 7] 4−. The pyrophosphates are mostly water-soluble. Likewise, tripolyphosphoric acid H 5 P 3 O 10 yields at least five anions [H 5−k P 3 O 10] k−, where k ranges from 1 to 5, including tripolyphosphate [P 3 O 10] 5−. Tetrapolyphosphoric acid H 6 P 4 O 13 yields at least six anions, including ...

The second and third pK a 's of phosphoric acid, pK a2 and pK a3, are 7.2 and 12.37, respectively. It follows that HPO 2− 4 and PO 3− 4 are sufficiently basic to serve as ligands. The examples below confirm this expectation. Molecular metal phosphate complexes have no or few applications.
[12] α-Mn 2 O 3 undergoes antiferromagnetic transition at 80 K. [13] γ-Mn 2 O 3 has a structure related to the spinel structure of Mn 3 O 4 where the oxide ions are cubic close packed. 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]
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 .
