Chemical compound

Gold(III) fluoride, AuF3, is an orange solid that sublimes at 300 °C. It is a powerful fluorinating agent. It is very sensitive to moisture, yielding gold(III) hydroxide and hydrofluoric acid.

Preparation

AuF3 can be prepared by reacting AuCl3 with F2 or BrF3.

Structure

The crystal structure of AuF3 consists of spirals of square-planar AuF4 units.
