首次合成和离析了八种以缺位型Dawson结构钼磷杂多阴离子为配体的稀土杂多蓝K17H2[Ln-(P2Mo17O61)2].nH2O和K17H4[Ln(P2Mo17O61)2].nH2O(Ln=La, Pr, Sm,Yb)。通过元素分析、电位滴定、红外光谱、紫外光谱、极谱、循环伏安、X射线光电子能谱、热重-差热分析和电子顺磁共振对杂多蓝进行了表征。实验结果表明,杂多阴离子还原为杂多蓝后, 性质发生了某些变化, 但结构基本不变, 配体P2Mo17O^1^061仍为α2型。

Eight heteropoly blues K17H2[Ln (P2Mo17O61)2].nH2O and K17H4[Ln(P2Mo17O61)2].nH2O (Ln = La, Pr, Sm, Yb) were synthesized and characterized by elemental analyses, potentiometric titration, IR, UV, polarog., cyclic voltammetry, XPS, x-ray powder diffraction, thermal analyses, and ESR. The properties of these series of heteropoly blues are different from those of their oxidized form, but no great changes in their structures were observed The ligand P2Mo17O6110- remains a2-isomer's configuration.
