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 .
IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
Robertsite, Ca 3 (Mn 3+) 4 [(OH) 3 | (PO 4) 2] 2 ·3(H 2 O) (alternatively formulated Ca 2 (Mn 3 (PO 4) 3 O 2)(H 2 O) 3), is a secondary phosphate mineral named for Willard Lincoln Roberts (1923–1987), mineralogist and professor at South Dakota School of Mines in Rapid City, South Dakota.
[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 antiferromagnetic with a Néel temperature of 210 K.
