Abstract
Luminescence lifetime of Eu(III) in complexes with four dicarboxylic (imino dicarboxylic, diglicolic, thioglycolic and dipicolinic) acids having potentially liganding donor atoms have been measured in H{sub 2}O and D{sub O} solutions. Luminescence lifetimes have been used for identification of the inner-sphere interactions between Eu(III) and the ligands, providing the number of water molecules coordinated to the Eu(III) ion. On the basis of hydration numbers calculated for the complexes studied as well as analysis of the FTIR spectra of the DGA ligands and their Tb(III) complexes, the role of the donor atoms (N, O, S) in complexation of lanthanide ions is discussed. The results show that the donor atoms of nitrogen and oxygen are bonded to lanthanide ions, in tridentate - dipicolinic, diglicolic and iminodiacetic acid ligands, whereas sulfur is not bonded to these ions, thus tioglycolic acid coordinates as a bidentate ligands.
