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.[5]
