报道了钴取代的钼硅稀土二电子杂多蓝Ｌｎ２Ｈ２［ＳｉＭｏ１１Ｃｏ（Ｈ２Ｏ）Ｏ３９］·ｎＨ２Ｏ，（Ｌｎ＝Ｌａ，Ｃｅ，Ｐｒ，Ｎｄ，Ｓｍ，Ｇｄ）的制备和离析方法，并通过元素分析、红外光谱、紫外－可见光谱、循环伏安、热重－差热分析、Ｘ射线光电子能谱、电子顺磁共振、２９Ｓｉ核磁共振和磁化率等对产物进行了表征及性质研究．结果表明，杂多蓝的结构与其母体杂多酸相比，结构上发生轻微的畸变，还原过程中，Ｃｏ２＋及Ｌｎ３＋均未变化
The preparation and isolation methods of cobalt-substituted molybdenum-silicon rare earth dianhydride blue Ln2H2 [SiMo11Co (H2O) O39] · nH2O, (Ln = La, Ce, Pr, Nd, Sm, Gd) were reported. Through elemental analysis, The products were characterized and characterized by FT-IR, UV-Vis, cyclic voltammetry, TG-DTA, XPS, EPR, 29Si NMR and magnetic susceptibility. The results showed that the structure of heteropoly blue slightly distorted its structure compared with that of its parent heteropolyacid. During the reduction process, Co2 + and Ln3 + did not change
