ABSTRACT

Ni2F5 was prepared by thermal decomposition of R-NiF3 at 373 K or by reduction of R-NiF3 with xenon or XeF2. Reaction of Ni2F5 in anhydrous HF (aHF) acidified with AsF5 yielded Ni(AsF6)2 and F2 while Ni2F5 disproportionated in aHF made basic with KF yielding NiF2 and K2NiF6. Ni2F5 is able to oxidize xenon to XeF2 and fluorinate C3F6 to C3F8. Ni2F5 is most probably playing an important role in the electrochemical fluorination.
