“…Lutetium is the heaviest and the smallest element of all the lanthanides [ 1 , 2 ]. Natural lutetium exists in two isotopic forms—in the form of a stable isotope 175 Lu and a radioactive isotope 176 Lu, which is used for radioisotope dating [ 3 ]. 177 Lu is one of the most attractive isotopes in clinical nuclear medicine for the diagnosis and therapy of cancer [ 4 ].…”

Three pyrrolidine-derived phenanthroline diamides were studied as ligands for lutetium trinitrate. The structural features of the complexes have been studied using various spectral methods and X-ray. The presence of halogen atoms in the structure of phenanthroline ligands has a significant impact on both the coordination number of lutetium and the number of solvate water molecules in the internal coordination sphere. The stability constants of complexes with La(NO3)3, Nd(NO3)3, Eu(NO3)3, and Lu(NO3)3 were measured to demonstrate higher efficiency of fluorinated ligands. NMR titration was performed for this ligand, and it was found that complexation with lutetium leads to an approximately 13 ppm shift of the corresponding signal in the 19F NMR spectrum. The possibility of formation of a polymeric oxo-complex of this ligand with lutetium nitrate was demonstrated. Experiments on the liquid–liquid extraction of Am(III) and Ln(III) nitrates were carried out to demonstrate advantageous features of chlorinated and fluorinated pyrrolidine diamides.
