摘要： 本文报道了镧系元素的杂多钨砷酸钾K11[Ln(AsW11O39)2]·xH2O(Ln:La、Ce、Pr、Nd、Sm)的合成方法和X-射线粉末衍射、红外及拉曼光谱、X-光电子能谱及有效磁矩的研究结果。

Abstract: The polytungstoarsenate[Ln(Asw11O39)2]11-(Ln:La3+,Ce3+,Pr3+,Nd3+,Sm3+) are reported.Their IRand Raman spectra are discussed.Some vibrational bands show a tendency to higher frequency from La to Sm.X-ray powder diffraction patterns demonstrate that some d-spacings decrease with La→Sm,which is consistent with Lanthanide contration.Chemical shifts in XPSwere observed.
