  摘要：

  Y(III) and lanthanide(III) mesaconates were prepared as crystalline solids with general formula Ln(2)(C5H4O4)(3).nH(2)O, where n=7 for La-Pr, n=4 for Y, Nd-Ho, n=8 for Er-Lu. IR spectra of the prepared mesaconates suggest that carboxylate groups are bidentate bridging anf chelating. During heating the hydrated complexes are dehydrated in one (Y, Nd-Lu) or two steps (La-Pr) and then decompose directly to oxides (Y, Ce, Pr, Sm, Gd-Lu) or with intermediate formation Ln(2)O(2)CO(3) (La, Nd, Eu).
