| Description | The luminescence lifetimes of europium(III) complexes with new monophosphorus acid derivatives of H4dota were measured by means of time-resolved laser-induced luminescence spectroscopy in H2O and D2O. The hydration numbers of these complexes were estimated using different empirical equations [Horrocks and Sudnick (1979) J. Am. Chem. Soc. 101 (1979) 334; Choppin and Barthelemy(1989) Inorg. Chem. 28, 33543357; Choppin and Bunzli Lanthanide probes in life, chemical and earth sciences. Theory and practice (1989); Kimura and Kato J. Alloys Comp. 275277 (1998) 806; Parker (1999) J. Chem. Soc., Perkin Trans. 2, 493503; Supkowski and Horroks (2002) Inorg. Chim. Acta. 340, 4448]. It was shown that all the relationships gave similar results with a satisfactory precision. The hydration numbers of complexes of H3do3a and H4dota agreed with the literature values. One water molecule is coordinated in complexes of the new ligands. |
