Palladium(II) fluoride, also known as palladium difluoride, is the chemical compound of palladium and fluorine with the formula PdF2.
PdF2 is prepared by refluxing palladium(II,IV) fluoride, PdII[PdIVF6], with selenium tetrafluoride, SeF4.
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.
Palladium fluoride is an insoluble powder used in infrared optical sensors, [5] and in situations where reactivity to oxygen makes palladium oxide unsuitable.
