【Abstract】 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.更多还原
