Abstract

A series of europium (III) mixed ligand complexes containing phenanthroline, benzoic acid and their derivatives, respectively, as ligands, were investigated by Mössbauer spectroscopy. The substituents changed the electron density on the donor atoms of the ligands by their electrophilic or nucleophilic nature and changed the stereochemistry of the coordination sphere by their different space requirement. Both effects were reflected in the isomer shift values. The basicity changes on the donor atoms due to the substituents were characterized by the Hammett 6 values of latters. The correlation between Eu isomer shifts and the Hammett 6 values of the corresponding substituents on the ligands of otherwise analogous europium (III) compounds indicated the binding mode in the complexes /1/.
