Palladium(II) fluoride, also known as palladium difluoride, is the chemical compound of palladium and fluorine with the formula PdF₂.

Synthesis

PdF₂ is prepared by refluxing palladium(II,IV) fluoride, Pd^II[Pd^IVF₆], with selenium tetrafluoride, SeF₄.

Pd[PdF₆] + SeF₄ → 2PdF₂ + SeF₆

Structure and paramagnetism

Like its lighter congener nickel(II) fluoride, PdF₂ adopts a rutile-type crystal structure, containing octahedrally coordinated palladium, which has the electronic configuration t⁶
_2g e²
_g. This configuration causes PdF₂ to be paramagnetic due to two unpaired electrons, one in each e_g-symmetry orbital of palladium.
