摘要
合成了六种过渡金属Ｎｉ 取代的钼硅杂多蓝稀土盐配合物，Ｌｎ２Ｈ２［ＳｉＭｏ１１Ｎｉ（Ｈ２Ｏ）Ｏ３９］·ｎＨ２Ｏ（ 其中Ｌｎ＝ Ｌａ，Ｃｅ，Ｐｒ，Ｎｄ，Ｓｍ ，Ｇｄ），通过ＩＲ、ＵＶ、极谱、循环伏安、ＴＧ－ ＤＴＡ、ＥＳＲ、２９Ｓｉ ＮＭＲ、ＸＰＳ、磁化率等对杂多蓝进行了表征．实验结果表明，杂多酸盐还原为杂多蓝后，基本结构发生轻微畸变，Ｎｉ２＋ 及Ｌｎ３＋
Six rare earth molybdosilicic heteropoly blues substituted by nickel, Ln 2H 2[SiMo 11 Ni(H 2O)O 39 ]· n H 2O(Ln=La,Ce,Pr,Nd,Sm,Gd)have been prepared and systematically characterized by IR, UV, CV, TG-DTA,ESR, 29 Si NMR,XPS, polarography and magnetic susceptibility. Based on the experimental results, it is reported that the reduced products (heteropoly blues) do not change their structures compared with unreduced compounds. Ni 2+ and Ln 3+ do not take part in the reduced processes.
