Abstract

New solid complexes of La(III), Ce(III), Tm(III), Yb(III) and Lu(III) with quercetin-5_- -sulfonic acid at pH 1.4-1.5 were obtained. On the basis of the elementary analysis and thermogravimetric investigation, the following composition of the compounds was determined: Ln(C15H9O10S) 3_nH2O (n = 14H2O - La, Ce; n = 13H2O - Tm, Yb, Lu).UV and VIS suggest that complexes of CT type were acquired. IR spectra and magnetic and thermogravimetric investigations demonstrate that the obtained complexes are hexa-coordinated. Groups 3OH and 4CO of the ligand participate in binding Ln(III).
