有机/杂多酸-钕配合物的合成、表征及电化学性质研究

Study on Synthesis,Characterization and Electrochemical Behavior of Organic/Heteropolyacid Neodymium Complex

采用水热法合成了以2,6-吡啶二羧酸及杂多酸磷钼酸为配体的钕的新型配合物Nd(C7H5NO4)(PMo12O40)·6H2O。通过元素分析、红外光谱、紫外光谱和热重分析对其进行了结构表征,结果表明,该配合物的紫外光谱在259nm处有明显的吸收。采用循环伏安法对配合物进行电化学性质研究表明,在-0.8^-0.1V的电势范围内,配合物具有电化学活性。

A novel complex Nd（C7H5NO4） （PMo12O40） · 6H2O was constructed from polyoxoanion clusters and Nd（Ⅱ）-2,6-pyridinedicarboxylic acid coordination complex fragments under hydrothermal conditions.The complex was characterized by elemental analysis,IR,UV and thermal gravimetric analysis.The results showed that UV spectrum of the complex had a significant absorption at 259 nm.In addition,electrochemical behavior of the complex was studied by cyclic voltammetry and good electrochemical activity was observed in the range of-0.8～-0.1 V.
