摘要
文报道利用循环伏安法和紫外可见光谱法测定了过渡金属钼、镧系元素铕和铒与Ｎ、Ｎ┐二乙基二硫代氨基甲酸根（ｄｔｃ）构成的八配位离子对配合物：［Ｍｏ（ｄｔｃ）４］［Ｅｕ（ｄｔｃ）４］和［Ｍｏ（ｄｔｃ）４］［Ｅｒ（ｄｔｃ）４］的氧化还原特性和光谱性质。实验证实，配合物的配正离子［Ｍｏ（ｄｔｃ）４］＋比配负离子［Ｅｕ（ｄｔｃ）４］－和［Ｅｒ（ｄｔｃ）４］－具备更好的稳定性和氧化还原可逆性，同时利用现场光谱电化学法测定了配正离子氧化还原反应的电子得失个数、标准式量电位和反应速率常数。
Redox and spectroscopic properties of the eightcoordination complexes of the transition element Mo and lanthanide element Eu and Er with N,Ndiethyldithiocarbamate (dtc) were characterized by cyclic voltammetry and UV Vis absorptive spectra. The complex cation [Mo(dtc) 4] + is more stable than the complex anions [Eu(dtc) 4] - and [Er(dtc) 4] - and possesses good redox reversibility. The electron exchange number, formal potential and rate constants of redox reactions for the complex cation were obtained by insitu spectroelectrochemistry.
