Caesium hexafluorocobaltate(IV)

Caesium hexafluorocobaltate(IV) is a rare example of cobalt(IV) complexs with the chemical formula Cs₂CoF₆. It can be synthesized by the reaction of Cs₃[(CoCl₄)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]
