Description Electrochemical properties of LnIII complexes with H2DO2A and H3DO3A ligand make them perfect candidates for use in many chemical, biological and environmental systems. H2DO2A and H3DO3A are hexa- and heptadentate ligands forming very stable binary complexes with europium(III) ion, where three, resp. two coordination sites are occupied by water molecules. These complexes form ternary complexes with small tri- and bidentate ligands, e.g. carbonate, oxalate, phosphate, etc. Different stability constants of those ternary complexes can be utilized for electrochemical selective determination of anions.
