Palladium(II) fluoride, also known as palladium difluoride, is the chemical compound of palladium and fluorine with the formula PdF<sub>2</sub>.
Like its lighter congener nickel(II) fluoride, PdF<sub>2</sub> adopts a rutile-type crystal structure, containing octahedrally coordinated palladium, which has the electronic configuration t e. This configuration causes PdF<sub>2</sub> to be paramagnetic due to two unpaired electrons, one in each e<sub>g</sub>-symmetry orbital of palladium.
PdF<sub>2</sub> is prepared by refluxing palladium(II,IV) fluoride, Pd<sup>II</sup>[Pd<sup>IV</sup>F<sub>6</sub>], with selenium tetrafluoride, SeF<sub>4</sub>.
Palladium fluoride is an insoluble powder used in infrared optical sensors, and in situations where reactivity to oxygen makes palladium oxide unsuitable.
