Caesium hexafluorocobaltate(IV) is a rare example of cobalt(IV) complexs with the chemical formula Cs
2
CoF
6
. It can be synthesized by the reaction of Cs
3
[(CoCl

)Cl]
and fluorine.[1]

It has cubic K2PtCl6 structure, with the lattice constant a = 8.91 Å, and the length of Co-F bond is 1.73 Å. Its ferromagnetic is complex and the ground state of Co(IV) is 2T2.[2]
