fluorine Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative reactive element, it is extremely reacti ...

. It has the empirical formula PdF₃, but is better described as the

mixed-valence compound Mixed valence complexes contain an element which is present in more than one oxidation state. Well-known mixed valence compounds include the Creutz–Taube complex, Prussian blue, and molybdenum blue. Many solids are mixed-valency including in ...

palladium(II) hexafluoropalladate(IV), Pd^II d^IVF₆ and is often written as Pd dF₆or Pd₂F₆.

Synthesis

Pd dF₆is the most stable product of the reaction of fluorine and metallic palladium. :2 Pd + 3 F₂ → Pd dF₆

Structure and properties

Pd dF₆is paramagnetic, and both Pd(II) and Pd(IV) occupy octahedral sites in the

crystal structure In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions or molecules in a crystal, crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric pat ...

. The Pd^II-F distance is 2.17 Å, whereas the Pd^IV-F distance is 1.90 Å.
