Apparently, permanganyl fluoride is stable, and easily formed, be adding KMnO4 into HF
(I presume anhydrous HF is meant) in a similar way to the synthesis of permanganic anhydride via KMnO4+conc.H2SO4.

I imagine this would be an oxidising agent of the most ferocious variety (FMnO7?), does anyone have any more information on this compound before I get busy? Is it a liquid or a solid, there is only three, irrelevant results spewed forth from the abyss that is google, and
I am worried about it's actual stability (I.E permanganic anhydride is 'stable', but tends to blow up in a cloud of ozone in one's face)

I really wouldn't want to synthesise an interesting looking compound and then then have it explode in a dirty great plume of HF or F in my face, that would bee a terrible waste of KMnO4 and HF...
