Caesium hexafluorocobaltate(IV) is a salt (chemistry), salt with the chemical formula . It can be synthesized by the reaction of and fluorine. The salt contains rare example of cobalt(IV) complex (chemistry), complex, i.e. [CoF₆]^2-. It has cubic Potassium hexachloroplatinate, K₂PtCl₆ structure, with the lattice constant a = 8.91 Å, and the length of Co-F bond is 1.73 Å. The complex is ferromagnetic and the ground state of Co(IV) is T_2g³E_g².
