Palladium(II) fluoride, also known as palladium difluoride, is the chemical compound of palladium and fluorine with the formula PdF2.
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 t e. This configuration causes PdF2 to be paramagnetic due to two unpaired electrons, one in each eg-symmetry orbital of palladium.
Synthesis PdF2 is prepared by refluxing palladium(II,IV) fluoride, PdII[PdIVF6], with selenium tetrafluoride, SeF4.
Pd[PdF6] + SeF4 → 2PdF2 + SeF6
Applications Palladium fluoride is an insoluble powder used in infrared optical sensors, and in situations where reactivity to oxygen makes palladium oxide unsuitable.
