[Bu_4N]_3[Mo_2FeS_8O]·(CH_2OH)_2簇合物的合成、结构和性质研究

Studies on Synthesis, Structure and Properties of the Cluster Compound, [Bu_4N]_3[Mo_2FeS_8O]·(CH_2OH_2)

(NH_4)_2MoS_4、FeCl_3与乙二醇钠在乙二醇溶液中反应,再与Bu_4NBr作用可得到一种Mo-Fe-S簇合物[Bu_4N]_3[Mo_2FeS_8O]·HOCH_2CH_2OH,其结构经X光晶体结构分析确定。并测定其红外光谱、紫外光谱、Mossbauer谱和电化学性质。该化合物可催化KBH_4转化乙炔还原为乙烯的反应。

Reaction of (NH_4)_2MoS_4 and FeCl_3 with HOCH_2CH_2ONa in ethylene glycol solution followed by treatment with Bu_4NBr gave a Mo--Fe--S cluster, [Bu_4N]_3[Mo_2FeS_8O]. (CH_2OH)_2, which was characterized by single erystal X-ray diffraction analysis, Its IR, UV-Vis Mossbauer spectra and electrochemical properties were recorded. The complex showed catalystic activity in the reduction of acetylene with KBH_4.
