Mixed-ligand complexation of iron(III) ethylenediaminetetraacetate with iminodiacetate and ethylenediamine in aqueous solution
摘要:
The formation of the heteroleptic complexes FeEdtaIda(3-) and FeEdtaEn(-)(Ida(2-) is the iminodiacetate anion and En is ethylenediamine) was examined by direct calorimetry, pH potentiometry, and spectrophotometry at 298.15 K and the ionic strength I = 0.5 (KNO3). A possible way of coordination of the ligands in the heteroleptic complexes was discussed.
