Lutetium(III) chloride or lutetium trichloride is the chemical compound composed of lutetium and chlorine with the formula LuCl3. It forms hygroscopic white monoclinic crystals[3] and also hydroscopic hexahydrate LuCl3·6H2O[5] . Anhydrous lutetium(III) chloride has the YCl3 (AlCl3) layer structure with octahedral lutetium ions.[6]


Pure lutetium metal can be produced from lutetium(III) chloride by heating it together with elemental calcium: [7]

2LuCl3 + 3Ca → 2Lu + 3CaCl2
