Ytterbium sulfide is a binary inorganic compound of ytterbium and sulfur with the chemical formula Yb
2S
3.^[1]

Synthesis

Synthesis is by reaction of pure substances in an inert atmosphere at 450–800 °C:

2Yb + 3S → Yb
2S
3

Or by passing hydrogen sulfide through heated ytterbium(III) oxide

Yb
2O
3 + 3H
2S → Yb
2S
3 + 3H
2O

Ytterbium trisulfide forms yellow crystals of rhombic symmetry, and cell parameters a = 0.678 nm, b = 0.995 nm, c = 0.361 nm.^[2]

The compound is used in the production of ceramics and as a catalyst.^[3]
