When concentrated sulfuric acid is added to solid potassium permanganate, Mn2O7 (Manganese heptoxide) is formed.
Mn2O7 is a green volatile oil, wich is an extremely strong oxidiser and almost any organic material will ignite on contact. Here this is demonstrated with a glass rod, wetted with ethanol.
WARNING: manganese heptoxide is very hazardous and should only be prepared in very small qunatities.
Well, the main reason is because it is the anhydride of permanganic acid. Meaning that the manganese atoms are in their highest oxidation state, and there is a weak Mn-O-Mn bond between two fully oxidized Mn atoms...Hmm I suppose that was a bit redundant, wasn't it?
I gotta type fast here, cause I gotta get off here, but it does have to do with the anhydride linkage...why not just google it?Not tryin to be a dick, I'd gladly explain, but I really have to get off here now. Hope that helped!

Can someone explain why manganese heptaoxide is such a strong oxidizer? I mean most oxiders, even perchlorates/chlorates and permanganates don't react that violently and easy witch reducing agents.

Sorry, accidentally pressed on the button. I actually prepared some Manganese heptoxide in a test tube once, it was pretty strong.
