Gold(III) fluoride, Au F₃, is an orange solid that sublimes at 300 °C.^[4] 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.^[3]

The crystal structure of AuF₃ consists of spirals of square-planar AuF₄ units.^[5]
