Potentiometric Study of Lanthanide Salicylaldimine Schiff Base Complexes
Abstract
<p>Formation of complexes between the lanthanide ions and N,N′- bis(salicylidene)-4-methyl-1,3-phenylenediamine ligand was studied in solution by pH potentiometry. The potentiometric titration was performed at 25.00 C in 0.1 mol·dm<sup>-3</sup>NaClO<sub>4</sub>ionic strength and in DMSO:water (30:70 v:v) solvent mixture. N,N′-bis(salicylidene)-4-methyl-1, 3-phenylenediamine ligand (H<sub>2</sub>L) occurs in three forms: fully or partially deprotonated and unionized. Computer analysis of potentiometric data indicated that in solution the lanthanide (Ln) complexes exist as LnL<sub>2</sub>, Ln(HL)<sub>2</sub>and Ln(H<sub>2</sub>L)<sub>2</sub>species. This observation appears to be in contrast to the solid-state behavior of these complexes prepared in a self-assembly process and structurally defined. Stability constants for La<sup>3+</sup>, Eu<sup>3+</sup>, Gd<sup>3+</sup>, Tb<sup>3+</sup>, Ho<sup>3+</sup>and Lu<sup>3+</sup>(Ln<sup>3+</sup>) complexes were determined. The order of stabilities of LnL<sub>2</sub>species in terms of metal ions is La<sup>3+</sup>> Eu<sup>3+</sup>≈ Gd<sup>3+</sup>= Tb<sup>3+</sup>< Ho<sup>3+</sup>< Lu<sup>3+</sup>with a prominent "gadolinium break". © 2013 Springer Science+Business Media New York.</p>
