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 a hygroscopic hexahydrate LuCl₃·6H₂O.^[6] Anhydrous lutetium(III) chloride has the YCl₃ (AlCl₃) layer structure with octahedral lutetium ions.^[7] Its isotopologue lutetium (¹⁷⁷Lu) chloride is used as a radioactive tracer for diagnosis and/or treatment in anti-cancer therapies.^[8]

Reactions

Pure lutetium metal can be produced from lutetium(III) chloride by heating it together with elemental calcium:^[9]

2 LuCl₃ + 3 Ca → 2 Lu + 3 CaCl₂
