Chemical compound
Ytterbium(II) sulfide is a binary
inorganic compound of
ytterbium and
sulfur with the chemical formula YbS.
[1]
[2]
Synthesis
Synthesis of ytterbium(II) sulfide can be via a reaction of pure substances in an
inert atmosphere:
[3]
- Yb + S → YbS
An alternative synthesis is by
comproportionation of
ytterbium(III) sulfide and ytterbium metal in
vacuum at 1000–1100 °C:
- Yb2S3 + Yb → 3YbS
Physical properties
Ytterbium(II) sulfide forms black crystals of cubic symmetry,
space group Fm3m, cell parameter a = 0.5658 nm, Z = 4.
[4]
Ytterbium(II) sulfide demonstrates semiconductor behavior.
