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
Dissolving lutetium oxide in nitric acid:
- [math]\displaystyle{ \mathsf{ Lu_2O_3 + 6HNO_3 \ \xrightarrow{90^oC}\ 2Lu(NO_3)_3 + 3H_2O } }[/math]
To obtain anhydrous nitrate, the powdered metal is added to nitrogen dioxide dissolved in ethyl acetate:
- [math]\displaystyle{ \mathsf{ Lu + 3N_2O_4 \ \xrightarrow{77^oC}\ Lu(NO_3)_3 + 3NO } }[/math]
Physical properties
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
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:
- [math]\displaystyle{ \mathsf{ Lu(NO_3)_3 + 6 NH_4F \ \xrightarrow{}\ (NH_4)_3[LuF_6]\downarrow + 3NH_4NO_3 } }[/math]
Applications
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.
