Spectroelectrochemical studies of Mo（dtc）4Eu（dtc）4 and Mo（dtc）4Er（dtc）4

摘要

＜正＞ Redox and spectroscopic properties of the eight-coordination complexes of molybdenum and the rare-earth elements Eu or Er with N,N-diethyldithiocarbamate （dtc） were characterised by cyclic voltamrnetry and UV-visible absorption spectra.The complex cation [Mo（dtc）4]+ is more stable than the complex anions [Eu（dtc）4]-and [Er（dtc）4]-in redox processes,and possesses good redox reversibility.The electron transfer number,formal standard electrode potential in the redox process for the complex cation and its diffusion coefficients were obtained by in aitu spectroelectro-chemistry.
