Ytterbium(II) fluoride is a binary inorganic compound of ytterbium and fluorine with the chemical formula YbF
2.[2][3][4]
Synthesis
Ytterbium(II) fluoride can be obtained by reacting ytterbium(III) fluoride with ytterbium or hydrogen.
- 2YbF
3 + Yb → 3YbF
2 - 2YbF
3 + H
2 → 2YbF
2 + 2HF
- 2YbF
Physical properties
Ytterbium(II) fluoride is a gray solid and crystallizes in the so-called fluorite type analogous to calcium fluoride with a unit cell a axis of 559.46 pm. In the crystal structure of ytterbium(II) fluoride, the Yb2+ cation is surrounded by eight F− anions in the form of a cube, which is tetrahedrally surrounded by four Yb2+.[5]
