Lutetium(III) nitrate is an inorganic compound, a salt of lutetium and nitric acid with the chemical formula Lu(NO3)3. The compound forms colorless crystals, dissolves in water, and also forms crystalline hydrates.[1] The compound is poisonous.[2]
Synthesis
[edit ]Dissolving lutetium oxide in nitric acid:
- {\displaystyle {\mathsf {Lu_{2}O_{3}+6HNO_{3}\ {\xrightarrow {90^{o}C}}\ 2Lu(NO_{3})_{3}+3H_{2}O}}}
To obtain anhydrous nitrate, the powdered metal is added to nitrogen dioxide dissolved in ethyl acetate:
- {\displaystyle {\mathsf {Lu+3N_{2}O_{4}\ {\xrightarrow {77^{o}C}}\ Lu(NO_{3})_{3}+3NO}}}
Physical properties
[edit ]Lutetium(III) nitrate forms colorless hygroscopic crystals.
Forms crystalline hydrates of the composition Lu(NO3)3•nH2O, where n = 3, 4, 5, 6.[3]
Chemical properties
[edit ]The hydrated lutetium nitrate thermally decomposes to form LuONO3 and decomposes to lutetium oxide upon further heating.[4]
The compound forms ammonium hexafluoroluthenate with ammonium fluoride:
- {\displaystyle {\mathsf {Lu(NO_{3})_{3}+6NH_{4}F\ \xrightarrow {} \ (NH_{4})_{3}[LuF_{6}]\downarrow +3NH_{4}NO_{3}}}}
Applications
[edit ]Lutetium(III) nitrate is used to obtain metallic lutetium and also as a chemical reagent.
It is used as a component of materials for the production of laser crystals.
