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), Pd^II[Pd^IVF₆] and is often written as Pd[PdF₆] or Pd₂F₆.

Synthesis

Pd[PdF₆] is the most stable product of the reaction of fluorine and metallic palladium.

2Pd + 3F₂ → Pd[PdF₆]

Structure and properties

Pd[PdF₆] is paramagnetic and both Pd(II) and Pd(IV) occupy octahedral sites in the crystal structure. The Pd^II-F distance is 2.17 Å, whereas the Pd^IV-F distance is 1.90 Å.
