General description

Xenon fluoride may be obtained by interacting elemental xenon and fluorine in the temperature range of 473-523 oC and 5 absolute atmosphere. Xenon difluoride readily interacts with Lewis acid and forms complexes.

Application

Very useful fluorination agent. Xenon fluoride may be used as a fluorinating agent to analyze sulphur, selenium and tellurium by gas chromatography.

The existence of the trifluoroxenate(II) anion, XeF(3)(-), had been postulated in a prior NMR study of the exchange between fluoride ion and XeF(2) in CH(3)CN solution. The enthalpy of activation for this exchange, ΔH(⧧), has now been determined by use

The application of pressure, internal or external, transforms molecular solids into extended solids with more itinerant electrons to soften repulsive interatomic interactions in a tight space. Examples include insulator-to-metal transitions in O(2), Xe and I(2), as well as molecular-to-non-molecular transitions
