Gold(III) fluoride, Шаблон:Chem2, is an orange solid that sublimes at 300 °C.[1] 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.[2]
Structure
The crystal structure of AuF3 consists of spirals of square-planar AuF4 units.[3]
