Abstract
The aqueous complexation of lanthanide ions with citrate in pH 7.4 sol ution has been investigated with use of the lanthanide-induced shift a nd paramagnetic relaxation rate enhancement methods. The results show that citrate coordinates via hydroxyl and central carboxylate groups w ith lanthanide ions and forms 1:2 (Ln/cit) isostructural complexes thr ough the lanthanide series. A new possible coordination geometry deduc ed from our experimental data is suggested and discussed.
