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