Ytterbium(III) sulfide is a binary inorganic compound of ytterbium and sulfur with the chemical formula Yb₂S₃. It is a yellow solid of rhombic symmetry, and cell parameters a = 0.678 nm, b = 0.995 nm, c = 0.361 nm. ^[1]

Synthesis

Ytterbium(III) sulfide can be produced by treating metallic ytterbium with sulfur:

2Sm + 3S → Sm₂S₃

Once prepared, ytterbium(III) sulfide can be purified by chemical vapor transport using iodine. ^[2]

Ytterbium(III) sulfide can also be prepared by treating the sulfate with hydrogen sulfide at elevated temperatures: ^[3]

Yb₂(SO₄)₃ + 12 H₂S → Yb₂S₃ + 12 H₂O + 12 S
