- Molecular formula:Cl3Yb
- Molecular Weight:279.4
Anhydrous ytterbium(III) chloride can be produced by the ammonium chloride route. In the first step, ytterbium oxide is heated with ammonium chloride to produce the ammonium salt of the pentachloride:
Yb2O3 + 10NH4Cl → 2(NH4)2YbCl5 + 6H2O + 6NH3
In the second step, the ammonium chloride salt is converted to the trichlorides by heating in a vacuum at 350-400°C:
(NH4)2YbCl5 → YbCl3 + 2HCl + 2NH3
Yb2O3 + 10NH4Cl → 2(NH4)2YbCl5 + 6H2O + 6NH3
In the second step, the ammonium chloride salt is converted to the trichlorides by heating in a vacuum at 350-400°C:
(NH4)2YbCl5 → YbCl3 + 2HCl + 2NH3
