Potassium hexafluorocuprate(III)

Potassium hexafluorocuprate(III) is an chemical formula K3CuF6. It is a green paramagnetic solid, a relatively rare example of a copper(III) compound.[1]

Synthesis and structure

The compound is prepared by oxidizing the mixture of potassium chloride and cuprous chloride with fluorine:[2]

3 KCl + CuCl + 3 F2 → K3CuF6 + 2 Cl2

A variety of analogues are known.[3] The compound reacts with water easily, producing oxygen and copper(II) products.[4]
