镧系元素的杂多钨镓酸盐的合成与表征

Synthesis and Characterization of Bis(undecatungsto-gallate) Lanthanates of Potassium

合成了8种稀土钨镓杂多配合物 K_(11)[Ln(GaW_(11)O_(39)H_2)_2]·xH_2O(Ln=La,Ce,Pr,Nd,Sm,Eu,Gd,Dy),通过元素分析、红外光谱、钨—183核磁共振谱、电子自旋共振光谱、X 射线光电子能谱及电化学测定,对其进行了表征。

The complexes of K_(11)[Ln(GaW_(11)O_(39)H_2)_2]·xH_2O(Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Dy) are prepared from their lacunary precursor K_8GaW_(11)O_(39), and characterized by elemental analysis, IR,^(183)WNMR, ESR, XPS and electrochemistry.
