Palladium(II,IV) fluoride, also known as palladium trifluoride, is a chemical compound of palladium and fluorine. It has the empirical formula PdF3, but is better described as the mixed-valence compound palladium(II) hexafluoropalladate(IV), PdII[PdIVF6], and is often written as Pd[PdF6] or Pd2F6.{{Greenwood&Earnshaw2nd|pages=1152–1153}}{{Housecroft3rd|page=788}}
Synthesis
Structure and properties
Pd[PdF6] is paramagnetic, and both Pd(II) and Pd(IV) occupy octahedral sites in the crystal structure.{{ cite journal | journal = Acta Crystallogr. | year = 1957 | volume = 10 | pages = 63–69 | title = The crystal structures of the trifluorides of iron, cobalt, ruthenium, rhodium, palladium and iridium | first1 = M.
