Abstract: | The reactions of some rare-earth elements (La, Ce, Sm, Lu, Gd) and Am(III) with heteropolymolybdate anions are studied. The complexation rate constants of Am(III) in a solution with Al(OH)6Mo6O183- and Cr(OH)6MoO183-6 (1 = 18 ± 6 and 25 ± 5, respectively) are determined by spectral methods. The Ln[Al(OH)6Mo6O18] · nH2O, Eu[Cr(OH)6Mo6O18] · nH2O, and Am[Al(OH)6Mo6O18] · nH2O isostructural compounds are synthesized. The crystal structure of the Sm[Al(OH)6Mo6O18] · 11H2O complex was determined by the X-ray diffraction analysis. The results of spectroscopic and thermogravimetric studies of the obtained compounds are presented. |
