摘要
本文首次报道了K_(17)[Ln(P_2Mo_(17)O_(61))_2]·xH_2O(Ln=La^(3+),Ce^(3+),pr^(3+),Nd^(3+),Sm^(3+),Eu^(3+),Gd^(3+),Tb^(3+),Yb^(3+))的合成方法,取测定结果表明,与(?)系离子配位的配体P_2Mo_(17)O♂♀^-为α_2-型,Ln的配位数为8,推测其结构类似于K_(16)[Ce(Ⅳ)(α_2-P_2W_(17)O_(61))_2]·xH_2O,还进行了UV光谱、CV、极谱、TG-DTA及磁化率等性质的研究。
The preparation and the physical and chemical characterization of zH2O(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(P2Mo17Oδ1)2]17-are stable in the solution of the pH range 3. 2 - 5. 5. IR spectra show that the ligand isα2-PaMo17O61 40-, 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 UV spectrum, polarogram, CV, magnetic susceptibility and thermal stability of the complexes are studied. Also the properties of the complexes are discussed from the structure.
