Аннотация:The effect of introducing of a halogen substituent into the structure of 2,2'-bipyridyl-6,6-dicarboxamide on the stability of their europium complexes has been studied. It is shown that, regardless of the size of the halogen atom, one complex particle is formed, and the metal-ligand stoichiometry of the complex is 1:1. The stability constants of europium complexes have been determined. A decrease in the size of the halogen atom leads to an increase in the stability of the complexes due to steric hindrance diminishing.
