Caesium hexafluorocobaltate(IV) is a
salt with the chemical formula Cs
2CoF
6. 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. [CoF62-.
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]
