摘要

研究了膦酸酯的结构对其铽配合物稳定性的影响。结果表明，无论侧酯链的性质如何，都能形成一个配合物颗粒，配合物的金属配体化学计量比为1:1。测定了铽配合物的稳定常数。大体积取代基尺寸的增加导致配合物稳定性的增加。

Study of the complexation reaction between substituted [2,2'-bipyridine]-6,6'-diyl(phosphonates) and terbium ions

The influence of the structure of phosphonic acid esters on the stability of their terbium complexes was studied. It was shown that one complex particle was formed irrespective the nature of the side ester chain, and the metal-ligand stoichiometry of the complex was 1:1. The stability constants of the terbium complexes were determined. An increase in the size of the bulky substituent leads to an increase in the stability of the complexes.
