Heating MnO 2 in air at below 800 °C produces α-Mn 2 O 3 (higher temperatures produce Mn 3 O 4). [5] γ-Mn 2 O 3 can be produced by oxidation followed by dehydration of manganese(II) hydroxide. [5] Many preparations of nano-crystalline Mn 2 O 3 have been reported, for example syntheses involving oxidation of Mn II salts or reduction of MnO 2 ...
But in a periodic table in a Next Generation episode, it is shown as an element with chemical symbol Dt and atomic number 87, which is in reality francium. Star Trek: The Next Generation Technical Manual gives a chemical formula made of real and fictional elements, instead of treating dilithium as its own element. Divinium (E115) Call of Duty
Manganese(II) sulfide is a chemical compound of manganese and sulfur. It occurs in nature as the mineral alabandite (isometric), rambergite (hexagonal), and recently found browneite (isometric, with sphalerite-type structure, extremely rare, known only from a meteorite).
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 .

The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
