Abstract
The aqueous complexation of lanthanide complexes of citrate in pH 7.4 solutions has been studied by using lanthanide-induced shift and relax ation times measurement methods. These results indicate that citrate c oordinate via 3-hydroxyl and 3-carboxylate groups with lanthanide ions and form 1:2 (Ln/cit) isostructural complexes through lanthanide seri es. We suggest a new coordination geometry which is different from tha t described in literature.
