Caesium hexafluorocuprate is the inorganic compound with the chemical formula Cs2CuF6. It is a red solid that degrades upon contact with water. It was first prepared by heating CsCuCl
3 and caesium fluoride at 410 °C under 350 atmospheres of fluorine: [2]
The anion [CuF6]2- is a rare example of a copper(IV) complex. In terms of its electronic structure, the anion has a low-spin d7 configuration. It is thus susceptible to Jahn-Teller distortion. [3]
