Ammonium neodymium nitrate is a chemical compound with the chemical formula Nd(NH4)2(NO3)5.[1][2][3] The compound is classified as a rare earth metal salt, belonging to nitrates.[4]
Synthesis
The compound can be prepared by the reaction of neodymium oxide, nitric acid, and ammonium nitrate.[5]
Also, it can be made by a reaction of neodymium oxide or neodymium carbonate with ammonium nitrate, releasing water as a byproduct:[4]
- Nd2O3 + 6NH4NO3 → 2(NH4)2Nd(NO3)5 + 3H2O
Physical properties
Ammonium neodymium nitrate is soluble in water.
The compound forms a tetrahydrate of the composition Nd(NH4)2(NO3)5 • 4H2O—red-violet crystals that melt in their own crystallization water at 47 °C.
Chemical properties
The compound reacts with strong acids to form soluble complexes. It can release nitrogen oxides when decomposed.[4]
Uses
Ammonium neodymium nitrate is used as a precursor for the synthesis of many other neodymium compounds and also as a reagent for various chemical reactions.[5]
