摘要
报道了６种线型簇合物［Ｅｔ_４Ｎ］_２［Ｍ_２Ｍ′Ｓ_４Ｏ_４］（Ｍ＝Ｍｏ，Ｗ；Ｍ′＝Ｃｏ，Ｎｉ，Ｆｅ）的合成，通过对ＵＶ－Ｖ_（ｉｓ）、ＩＲ及ＸＰＳ光谱的对比分析，讨论了簇阴离子［Ｍ_２Ｍ′Ｓ_４Ｏ_４］~２－中心金属Ｍ′的ｄ电子结构、氧化态以及［Ｍ′Ｓ_４］的微环境，由此推测了簇阴离子构型，并讨论了化合物的稳定性．
Six linear clusters [Et_1N]_2[M_2M′S_4O_4](M=Mo,W;M′=Co, Ni, Fe)wereprepared and chracterized by means of UV-Vis, IR and XPS spectra. By comparing andstudying the spectra, the d electron configuration,valence of central metal M′and the mi-cro-environment of[M′S_4] are discussed. Based on this,the configuration of anion of theclusters was inferred and the stability of the clusters was discussed.
