Lutetium (III) chloride can also be synthesized directly from the elements lutetium and chlorine .

{\ displaystyle \ mathrm {2 \ Lu + 3 \ Cl_ {2} \ longrightarrow 2 \ LuCl_ {3}}}

properties

Lutetium (III) chloride and its hexahydrate are colorless solids. Both are soluble in water. Lutetium (III) chloride has a monoclinic crystal structure with the space group C 2 / m (No. 12) corresponding to that of aluminum (III) chloride . Template: room group / 12

use

Lutetium (III) chloride can be used to make pure lutetium.
