Ytterbium(III) sulfide is a binaryinorganic compound ofytterbium andsulfur with the chemical formulaYb2S3. It is a yellow solid of rhombic symmetry, and cell parameters a = 0.678 nm, b = 0.995 nm, c = 0.361 nm.[1]
Ytterbium(III) sulfide can be produced by treating metallic ytterbium with sulfur:
Once prepared, ytterbium(III) sulfide can be purified bychemical vapor transport usingiodine.[2]
Ytterbium(III) sulfide can also be prepared by treating the sulfate withhydrogen sulfide at elevated temperatures:[3]
