Ytterbium(III) sulfide

Ytterbium(III) sulfide is a binary inorganic compound of ytterbium and sulfur with the chemical formula Yb₂S₃.

Preparation

Ytterbium(III) sulfide can be obtained by reacting ytterbium and sulfur in an inert atmosphere at 450–800 °C:

2Yb + 3S → Yb₂S₃

It can also be prepared by passing hydrogen sulfide through heated ytterbium(III) oxide:

Yb₂O₃ + 3H₂S → Yb₂S₃ + 3H₂O

Physical properties

Ytterbium(III) sulfide forms yellow crystals of rhombic symmetry, and cell parameters a = 0.678 nm, b = 0.995 nm, c = 0.361 nm.
