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, PdII[PdIVF6], 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,[2][3] containing octahedrally coordinated palladium, which has the electronic configuration t6
2g e2
g. This configuration causes PdF2 to be paramagnetic[4] due to two unpaired electrons, one in each eg-symmetry orbital of palladium.

Applications

Palladium fluoride is an insoluble powder used in infrared optical sensors,[5] and in situations where reactivity to oxygen makes palladium oxide unsuitable.
