| Abstract: | The mixed-ligand complex formation in the systems Cd2 + Edta4–(CH2) n (NH2)2, n = 2 (En), 6 (L) has been NMR and calorimetrically studied in aqueous solution at 298.15 K and the ionic strength of I = 0.5 (KNO3). The thermodynamic parameters of formation of the CdEdtaL2−, CdEdtaHL−, (CdEdta)2L4−, and (CdEdta)2En4− complexes have been determined. The most probable coordination mode for the complexone and the diamine ligand in the mixed-ligand complexes was discussed. |
