Xenon hexafluoride is a noble gas compound with the formula XeF 6. It is one of the three binary fluorides of xenon that have been studied experimentally, the other two being XeF 2 and XeF 4. All known are exergonic and stable at normal temperatures. XeF 6 is the strongest fluorinating agent of the series. It is a colorless solid that readily ...
Xenon hexafluoroplatinate is the product of the reaction of platinum hexafluoride with xenon, in an experiment that proved the chemical reactivity of the noble gases.This experiment was performed by Neil Bartlett at the University of British Columbia, who formulated the product as "Xe + [PtF 6] −", although subsequent work suggests that Bartlett's product was probably a salt mixture and did ...
To prevent decomposition, the xenon tetroxide thus formed is quickly cooled into a pale-yellow solid. It explodes above −35.9 °C into xenon and oxygen gas, but is otherwise stable. A number of xenon oxyfluorides are known, including XeOF 2, XeOF 4, XeO 2 F 2, and XeO 3 F 2. XeOF 2 is formed by reacting OF 2 with xenon gas at low temperatures.
It is synthesized by the reaction of xenon hexafluoride (XeF 6) with nitrosyl fluoride (NOF): [2] XeF 6 + 2 NOF → (NO) 2 XeF 8. Other compounds containing the octafluoroxenate(VI) ion include its alkali metal salts, including Cs 2 XeF 8 and Rb 2 XeF 8, which are stable up to 400 °C. [3] [4]
Molybdenum hexafluoride and rhenium hexafluoride are liquids. The rest are volatile solids. Uranium hexafluoride in sealed glass. Metal hexafluorides are oxidants because of their tendency to release fluorines: for example, platinum hexafluoride was the first compound to oxidize molecular oxygen [68] and xenon. [69]

Xenon is a member of the zero-valence elements that are called noble or inert gases. It is inert to most common chemical reactions (such as combustion, for example) because the outer valence shell contains eight electrons. This produces a stable, minimum energy configuration in which the outer electrons are tightly bound. [60]
Platinum hexafluoride is the chemical compound with the formula Pt F 6, and is one of seventeen known binary hexafluorides. It is a dark-red volatile solid that forms a red gas. The compound is a unique example of platinum in the +6 oxidation state. With only four d-electrons, it is paramagnetic with a triplet ground state.
