Palladium(II) fluoride explained

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[Pd<sup>IV</sup>F<sub>6</sub>], with selenium tetrafluoride, SeF4.

Pd[PdF<sub>6</sub>] + SeF4 → 2PdF2 + SeF6

Structure and paramagnetism

Like its lighter congener nickel(II) fluoride, PdF2 adopts a rutile-type crystal structure,[1] [2] containing octahedrally coordinated palladium, which has the electronic configuration t e. This configuration causes PdF2 to be paramagnetic 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,[3] and in situations where reactivity to oxygen makes palladium oxide unsuitable.
