Ytterbium (III) fluoride (YbF ₃ ) is a salt of the rare earth metal ytterbium with hydrogen fluoride .

Extraction and presentation

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

${\displaystyle \mathrm {Yb_{2}O_{3}+6\ HF\longrightarrow 2\ YbF_{3}+3\ H_{2}O} }$

Alternatively, it can also be produced by reacting hydrofluoric acid with ytterbium (III) chloride .

properties

At room temperature , ytterbium (III) fluoride takes on the orthorhombic β-YF ₃ structure in the space group Pnma (space group no. 62) .
