Palladium(II,IV) fluoride, also known as palladium trifluoride, is a chemical compound of palladium and fluorine. It has the empirical formula PdF<sub>3</sub>, but is better described as the mixed-valence compound palladium(II) hexafluoropalladate(IV), Pd<sup>II</sup>[Pd<sup>IV</sup>F<sub>6</sub>], and is often written as Pd[PdF<sub>6</sub>] or Pd<sub>2</sub>F<sub>6</sub>.
Pd[PdF<sub>6</sub>] is paramagnetic, and both Pd(II) and Pd(IV) occupy octahedral sites in the crystal structure. The Pd<sup>II</sup>-F distance is 2.17 ÃÂ , whereas the Pd<sup>IV</sup>-F distance is 1.90 ÃÂ .
Pd[PdF<sub>6</sub>] is the most stable product of the reaction of fluorine and metallic palladium.
