Plasmachemical Syntheses of RuF 6 , RhF 6 , and PtF 6 .

Starting from the respective metal M , we have synthesized the hexafluorides M F 6 of M = Ru, Rh, and Pt by the use of a laser-based heating system and a remote fluorine plasma source using a mixture of Ar and NF 3 as the feed gas. The formation of the hexafluorides was confirmed by several different spectroscopic methods, including IR, Raman, UV/vis, and NMR spectroscopy. In addition, we present first experimental hints that RuF 6 is more reactive than PtF 6 , because RuF 6 is able to oxidize lower fluorides of platinum to PtF 6 .
