Caesium hexafluorocuprate is the
inorganic compound
An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bondsthat is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as ''inorganic chemistry''.
Inorgan ...
with the chemical formula . It is a red solid that degrades upon contact with water. It was first prepared by heating and
caesium fluoride at 410°C under 350 atmospheres of fluorine:
:2 CsCuCl
3 + 2 CsF + 5 F
2 → 2 Cs
2CuF
6 + 3 Cl
2
The anion
uF6sup>2- is a rare example of a copper(IV) complex. In terms of its electronic structure, the anion has a low-spin d
7 configuration. It is thus susceptible to
Jahn-Teller distortion.
