Gold(III) fluoride, AuF3, 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]
Structure
The crystal structure of AuF3 consists of spirals of square-planar AuF4 units.[5]
