Caesium hexafluorocobaltate(IV) is a salt with the chemical formula Cs2CoF6. It can be synthesized by the reaction of Cs
3[(CoCl
4)Cl] and fluorine.[1] The salt contains rare example of cobalt(IV) complex, i.e. [CoF6]2-.
It has cubic K2PtCl6 structure, with the lattice constant a = 8.91 Å, and the length of Co-F bond is 1.73 Å.[1] The complex is ferromagnetic and the ground state of Co(IV) is T2g3Eg2.[2]
