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.

Cadmium permanganate is an inorganic compound with the chemical formula Cd(MnO 4) 2 ... Cadmium permanganate can also be produced by reacting manganese heptoxide with ...
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.
