Xenon hexafluoroplatinate (IV) (XePtF 6 ) is a combination of the noble gas xenon , the noble metal platinum and the halogen fluorine .
history
Xenon hexafluoroplatinate was the first noble gas compound produced . It was discovered in 1962 by the American chemist Neil Bartlett . The synthesis attempt was stimulated by the observation that platinum hexafluoride PtF 6 forms the compound dioxygenyl hexafluoroplatinate O 2 + PtF 6 - with molecular oxygen O 2 . Since oxygen and xenon have similar ionization energies , the reaction should also be possible with xenon.
properties
Xenon hexafluoroplatinate is a mixture of different compounds. Xenon always has the oxidation state + II. Some of these compounds are XeF + PtF 6 - , XeF + Pt 2 F 11 - and Xe 2 F 3 + PtF 6 - . Like most noble gas compounds, xenon hexafluoroplatinate is very unstable and can therefore only be isolated at very low temperatures. When heated, it immediately decomposes into xenon and platinum hexafluoride.
