Lanthanide complexes with aromatic and polyheteroatomic macrocyclic ethers. Complexes with 1,4,7,10,13,16-hexaoxacyclooctadecane

Rare earth nitrate and chloride complexes with 18-crawn-6 in the medium of polar organic solvents have been synthesized. The physicochemical properties as well as the influence of rare earth character and lanthanide salt anion on the compostion and properties of the compounds prepared have been studied. It is established that complexes of metal:ligand=1:1 composition are formed independently on synthesis conditions. Anion has an affect on the degree of hydration of the complexes prepared as well as on their therm0l stability. Thermal investigations have been carried out and ways of complex thermodestruction have been determined
