Palladium tetrafluoride, structure

Although the linking through fluorine bridges is different from that in palladium tetrafluoride, the fluorine atom positions in vanadium tetrafluoride correspond approximately to a hexagonal close-packed array. The linking of octahedra leads to a complex layer structure, rather than the three-dimensional lattice of the palladium tetrafluoride arrangement. 

Although the number of tetrafluorides reported is as large as the number of di- and trifluorides (see Table III), this group of compounds is the least well characterized structurally of the transition metal fluorides. The synthesis of most of the expected tetrafluorides has been reported, with examples from titanium to manganese in the first, from zirconium to palladium (except for technetium) in the second, and from hafnium to platinum (except for tantalum) in the third series. Many of them have been little studied and, in general, they have not proved amenable to crystallographic structural analysis. 

The tetrafluorides of iridium, rhodium and palladium [13] have been established by the work reported in this paper and together with Ptp4 constitute a structurally related set.
