稀土元素钨钒磷酸根配合物的研究

STUDY ON TUNGSTEN-VANADIUM-PHOSPHATEHETEROPOLY COMPLEXES WITH LANTHANIDES

制备了一系列新型稀土元素钨钒磷四元杂多配合物。其分子通式为:K_(11)H_2[Ln(PW_(10)V_1O_(39)_2]·mH_2O(Ln=La^(3+)、Ce^(4+)、Pr^(3+)、Nd^(3+)、Sm^(3+)、Eu^(3+)、Gd^(3+)、Dy^(3+)、Yb^(3+))讨论了它们的XPS、NMR、ESR、UV、IR等波谱性质。结果表明,配体部分具有空位α—Keggin结构。

Tungstenvanadiumphosphate heteropoly complexes with lanthanides, K_(11)H_2[Ln(PW_(10)V_1 O_(39)_2]·mH_2O(Ln=La^(3+)、Ce^(4+)、Pr^(3+)、Nd^(3+)、Sm^(3+)、Eu^(3+)、Gd^(3+)、Dy^(3+)、Yb^(3+)) wene first synthesized The physical and chemical characters of the new preparative heteropoly compounds were studied by using xps.NMR,ESR, UV and IR,It was deduced that both tungstenvanadiumphosphate heteropoly ligands are of a defective α—Keggin structure.
