For evaluation of coefficients α M and α L value of pK a of ligands [31], stability constants of acetic and hydroxo complexes [32][33][34][35][36][37][38][39] of lanthanides have been used. All data used for calculation α M and α L demonstrated in Table S25.…”

The aqueous complexation of some lanthanides(III) and lanthanum(III) ions with quercetin and quercetinsulfanate are reported. The equilibrium stability constants for the formation of 1 : 1 monocomplexes Ln(III)-quercetin/ quercetinsulfanate (Ln(III)=La(III), Ce(III), Pr(III), Nd(III), Sm(III), Eu(III), Gd(III), Tb(III), Dy(III), Er(III), Tm(III), Yb(III)) were determine in an acetic buffered solution. The measurements were conducted by spectrophotometric method at 293 K and I = 1(NaClO 4). Structures of formed complexes were suggested with using DFT simulations.

Aqueous Complexation of Morin and Its Sulfonate Derivative with Lanthanum(III) and Trivalent Lanthanides

et al. 2019

View full text Add to dashboard Cite

The complexation of flavonoids Morin and morin-5'-sulfonic acid (MSA) with rare earth metals is studied in aqueous solution using absorption spectroscopy. In this research 50 conditional and 26 "true" equilibrium stability constants of monocomplex species were determined for various values of pH at constant ionic strength I=1 (NaClO4). The interactions are investigated for La3+ and 12 lanthanides (Ce3+,

“…Since the absorbance maximum remains invariant at different metal concentrations, the λ max position is therefore determined only by a specific ligand, and ε max only by the metal ion. According to literature, lanthanides easily form acetic [21][22][23][24][25][26] and hydroxo complexes, [27] and their equilibrium constants are summarized in Table 4. The coefficients of competing reactions have been calculated using Equation (2) and (3) [28] …”

This paper deals with spectrophotometric investigation on complexation of Y III , La III , Nd III , Sm III , Eu III , and Yb III metal ions with six heterocyclic substituted β-diketones. The stability constants of 36 monocomplex species was determined in aqueous solutions at 298 K and I = 0.25; it lay in the range from 5.14 to 9.76 logarithmic units. The influence of the natures of the metal and ligand on the stability constant along
