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[1]. Lutetium(III) chloride has the YCl3 (AlCl3) layer structure with octahedral lutetium ions.[5]
Pure lutetium metal can be produced from lutetium(III) chloride by heating it together with elemental calcium: [6]
