Enthalpies of complexation of diglycine (HL±) with Pr3+ and Sm3+ ions at 303.15 K and I = 0.5 (KNO3) have been determined by means of calorimetry. The thermodynamic parameters of the formation of diglycine complexes with Pr3+ and Sm3+ ions have been calculated at different molar ratios between metal and the ligand.
