Abstract: A series of polybassc lanthanide heteropoly complexes K10H3[Ln(SiMo11-nWnO39)2mH2O(where n = 2,4; Ln = La3+、Ce3+、Pr3+、Nd3+、Sm3+、Eu3+、Gd3+、Dy3+、Yb3+) were prepared. Their molecula formula were decided by elemental analysis and thermogravimctric analysis. Crystal structure and molecula structure of K10H3[La(SiMo9W2O392]·29H2O are determined using X-Ray single crystal analysis, space group P21/n, a=17.224(6)Å, b= 26.952(11)Å c=21.158(7)Å, β=103.76(3)°, Z=4, V= 9540.17(6)Å3, F(000)= 8663. Thermal decomposition arc investigated by means of IR spectrs, X-Ray powder diffraction and differential therm-al-thermogravimetric analysis. The results of acid-base titration show the complexes arc stable in the range pH = 2.5-6.1, in the meantime, oxidation-reduction, TR spectra, UV spectra, XPS spectra and X-Ray powder diffraction character of these complexes were also discussed.
