Complexes of salts of rare-earth metals with 18-crown-6 have been synthesized in media of polar organic solvents. Their physicochemical properties, as well as the influence of the nature of the rare-earth metals and the anions of the lanthanide salts on the composition and properties of the compounds obtained, have been studied. It has been established that complexes with a 1:1 metal:ligand ratio form, regardless of the synthesis conditions. The anion has an influence on the degree of hydration of the complexes obtained, as well as on their thermal stability. Thermal investigation have been carried out, and the paths of thermal degradation of the complexes have been determined.
