摘要: 本文首次报道了K17[Ln(P2Mo17O61)2]·xH2O(Ln=La3+,Ce3+,pr3+,Nd3+,Sm3+,Eu3+,Gd3+,Tb3+,Yb3+)的合成方法,取测定结果表明,与镧系离子配位的配体P2Mo17O610-为α2-型,Ln的配位数为8,推测其结构类似于K16[Ce(Ⅳ)(α2-P2W17O61)2]·xH2O,还进行了UV光谱、CV、极谱、TG-DTA及磁化率等性质的研究。

Abstract: The preparation and the physical and chemical characterization of K17[Ln(P2Mo17O61)2]·xH2O(Ln=La,Ce, Pr, Nd, Sm, Eu, Gd, Tb, Yb) are reported. The test of cation bedexchanger shows that the lanthanide cations are interior. Complexes [Ln(P2Mo17O61)2]17-are stable in the solution of the pHrange 3. 2-5. 5. IRspectra show that the ligand is α2-PaMo17O6110-, and the lanthanide cations are octahedral coordination. It is inferred that the complexes resemble the K17[Ce(Ⅳ) (α2-P2W17O61)2] ·xH2O in structure. The UVspectrum, polarogram, CV, magnetic susceptibility and thermal stability of the complexes are studied. Also the properties of the complexes are discussed from the structure.
