Complexes of neodymium and europium with amides and aminoxides were synthesized and characterized by complexometric analyses
with EDTA, CHN microanalytical procedures, IR absorption spectra, absorption spectra of neodymium complexes, emission spectrum
of europium compounds at 77 K, thermogravimetric analyses in N2 and differential scanning calorimetry (DSC) in N2. Infrared
spectroscopy results revealed that the nitrate molecules are bound to the central ions as bidentate. Thermogravimetric plots
indicated that the decomposition of the complexes occurs in the range 363-1163 K and resulted in the formation of Ln2O3 residues.
