Manganese(VII) oxide (manganese heptoxide) is an inorganic compound with the formula Mn 2 O 7. Manganese heptoxide is a volatile liquid with an oily consistency. It is a highly reactive and powerful oxidizer that reacts explosively with nearly any organic compound. It was first described in 1860. [1] It is the acid anhydride of permanganic acid.
Manganese may also form mixed oxides with other metals : Bixbyite, (Fe III,Mn III) 2 O 3, a manganese(III) iron(III) oxide mineral; Jacobsite, Mn II Fe III 2 O 4, a manganese(II) iron(III) oxide mineral; Columbite, (Fe II,Mn II)Nb 2 O 6, a niobate of iron(II) and manganese(II) Tantalite, (Fe II,Mn II)Ta 2 O 6, a tantalum(V) mineral group close ...
Manganese(II) oxide is an inorganic compound with chemical formula MnO. [2] It forms green crystals. The compound is produced on a large scale as a component of fertilizers and food additives .
Permanganic acid has also been prepared through the reaction of hydrofluorosilicic acid with potassium permanganate, [4] through electrolysis, and through hydrolysis of manganese heptoxide, though the last route often results in explosions. [5] Crystalline permanganic acid has been prepared at low temperatures as the dihydrate, HMnO 4 ·2H 2 O. [3]

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 .
Rhenium(VII) oxide, or rhenium heptoxide, is another oxide of rhenium. It is the anhydride form of perrhenic acid , and is the raw material for all rhenium compounds. [ 11 ] Solid Re 2 O 7 consists of alternating octahedral and tetrahedral Re centres.
Technetium (VII) oxide containing Technetium-99. Technetium(VII) oxide is the chemical compound with the formula Tc 2 O 7.This yellow volatile solid is a rare example of a molecular binary metal oxide, the other examples being RuO 4, OsO 4, and the unstable Mn 2 O 7.
