Chemical compound
Palladium(II,IV) fluoride , also known as palladium trifluoride , is a chemical compound of palladium and fluorine . It has the empirical formula PdF3 , but is better described as the mixed-valence compound palladium(II) hexafluoropalladate(IV), PdII [PdIV F6 ], and is often written as Pd[PdF6 ] or Pd2 F6 .[ 1] [ 2]
Pd[PdF6 ] is the most stable product of the reaction of fluorine and metallic palladium.[ 1]
2 Pd + 3 F2 → Pd[PdF6 ]
Structure and properties [ edit ]
Pd[PdF6 ] is paramagnetic , and both Pd(II) and Pd(IV) occupy octahedral sites in the crystal structure .[ 2] [ 3] The PdII -F distance is 2.17 Å, whereas the PdIV -F distance is 1.90 Å.[ 4]
