Abstract

Publisher Summary This chapter discusses recent advances in noble-gas chemistry. The chemistry of xenon originates from the reactions of the binary fluorides and falls into five main categories: (1) reactions in which the xenon fluoride acts as a fluorinating agent, (2) hydrolysis reactions yielding oxide fluorides, oxides, and oxygencontaining salts, (3) fluoride/anion metathesis reactions between the fluoride and an anhydrous acid, (4) reactions with fluoride ion acceptors, yielding fluorocations, and (5) reactions with fluoride ion donors, yielding fluoroanions. In general, the component molecules of all of the cationic/anionic complexes are linked together by fluorine bridges, which have a considerable degree of ionic character. However, Raman spectra of the complexes derived from the metal oxide tetrafluorides indicate that they are best formulated as essentially covalent structures. As in the case of xenon, one of the most interesting developments in krypton chemistry is the identification of bonds between noble-gas atoms and elements other than fluorine.
