Syntheses and some properties of dioxygenyl fluorometallate salts

Abstract

Twelve dioxygenyl salts of complex fluorometallate anions have been prepared by a simple thermal method; seven of these compounds are new. The salts have been characterized by combinations of powder X-ray crystallography, Raman spectroscopy, and molecular beam mass spectroscopy. They fall into two classes: compounds of strongly oxidizing hexafluorides and compounds of strong fluoride-ion acceptors. Mass spectra provide evidence for the independent existence of AuF₅.
