Bismuth ( III ) fluoride is a chemical bond between bismuth and fluorine. It has the chemical formula BiF3 and can be used for the preparation of bismuth ( V ) fluoride.

Production and representation

Bismuth ( III ) fluoride can be synthesized by reaction of bismuth ( III) oxide with hydrofluoric acid.

Also, the reaction with bismuth oxychloride is successful:

The reaction of bismuth ( III) hydroxide with aqueous hydrofluoric acid does not provide a pure bismuth (III) fluoride, but oxide fluorides.

Properties

Bismuth ( III ) fluoride is a white, crystalline solid. It has an orthorhombic crystal structure of ytterbium (III ) fluoride - type.
