Ytterbium (III ) fluoride ( YbF3 ) is a salt of the rare earth metal is ytterbium, with hydrogen fluoride.

Production and representation

Ytterbium (III ) fluoride can be obtained by reaction of ytterbium ( III) oxide with hydrogen fluoride.

Alternatively, the preparation by the reaction of hydrofluoric acid with ytterbium ( III) chloride is also possible.

Properties

At room temperature takes ytterbium (III ) fluoride, a β - YF3 the orthorhombic structure (space group Pnma ).
