Description
La(III), Ce(III), Pr(III) and Sm(III) form 1:1 and 1:2 complexes with DL-aspartic acid in 20% aq. dimethyl sulphoxide at μ = 0.1M (NaClO4) as revealed by pH-metric and conductometric titrations. Stabilities of the complexes follow the order: La3+<Ce3+<Pr3+<Sm3+. The overall changes in ΔG, ΔH and ΔS for the metal-ligand interaction have also been reported at 30deg C. (auth.)
