• The reduction potentials of Fe(acac)<SUB>3</SUB> and Eu(acac)<SUB>3</SUB> in DMF are shifted to more positive potentials by the addition of cations (Li<SUP>+</SUP> and Mg<SUP>2+</SUP>) to the supporting electrolyte of tetraethylammonium perchlorate. Studies of the complexes show that the effect is caused by coordinative relaxation reaction of the Fe(acac)<SUB>3</SUB><SUP>−</SUP> reduction product in which acetylacetonate ligand becomes transferred to the cation. However, in the case of Eu(acac)<SUB>3</SUB><SUP>−</SUP>, acetylacetonate ligands seemed to be completely stripped off. Cyclic voltammetric data indicate reduction and reoxidation processes of the complexes.
