Lanthanide(III) Complexes of Phosphorus Acid Analogues of H4DOTA as Model Compounds for the Evaluation of the Second-Sphere Hydration

Abstract

Structures of Ln(III) (especially Gd(III)) complexes with phosphorus acid derivatives of DOTA. having no coordinated water molecule were investigated in the solid state and in solution as well as influence of the complexes on the 2nd coordination sphere.
