Xenon fluoride. 7 languages. Español ... Three different xenon fluorides, all exergonic and stable, are known: Xenon difluoride, XeF 2; Xenon tetrafluoride, XeF 4 ...
The xenon fluorides behave as both fluoride acceptors and fluoride donors, forming salts that contain such cations as XeF + and Xe 2 F + 3, and anions such as XeF − 5, XeF − 7, and XeF 2− 8. The green, paramagnetic Xe + 2 is formed by the reduction of XeF 2 by xenon gas. [1] XeF 2 also forms coordination complexes with transition metal ...
The XeF + cation is formed by combining xenon difluoride with a strong fluoride acceptor, such as an excess of liquid antimony pentafluoride (SbF 5): XeF 2 + SbF 5 → XeF + + SbF − 6. Adding xenon gas to this pale yellow solution at a pressure of 2–3 atmospheres produces a green solution containing the paramagnetic Xe +
Bartlett synthesized xenon tetrafluoride (XeF 4) by subjecting a mixture of xenon and fluorine to high temperature. [9] Rudolf Hoppe, among other groups, synthesized xenon difluoride (XeF 2) by the reaction of the elements. [10] Following the first successful synthesis of xenon compounds, synthesis of krypton difluoride (KrF 2) was reported in ...

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 ...
