Lutetium(III) chloride orlutetium trichloride is thechemical compound composed oflutetium andchlorine with theformula LuCl3. It formshygroscopic whitemonoclinic crystals[3] and also a hygroscopic hexahydrate LuCl3·6H2O.[6] Anhydrous lutetium(III) chloride has theYCl3 (AlCl3) layer structure with octahedral lutetium ions.[7] Itsisotopologuelutetium (177Lu) chloride is used as aradioactive tracer for diagnosis and/or treatment in anti-cancer therapies.[8]
Pure lutetium metal can be produced from lutetium(III) chloride by heating it together with elementalcalcium:[9]
