本文报导了两种新的Mo—Fe—S原子簇化合物〔Et_4N〕_2〔MoFeS_4(SCN)_2(OCH_3)_2〕·3CH_3OH和〔Et_4N〕_3〔Mo_2FeS_8O(OCH_3)_2〕的合成和性质研究。实验中发现,化合物中Fe的相对含量越高,其催化乙炔还原为乙烯的活性也越高。还发现,体系的硷度对合成结果有重要影响。
In this paper, the synthesis and properties of two novel Mo-Fe-S clusters [Et_4N] _2 [MoFeS_4 (SCN) _2 (OCH_3) _2] · 3CH_3OH and [Et_4N] _3 [Mo_2FeS_8O (OCH_3) _2] have been reported. It was found in the experiment that the higher the relative content of Fe in the compound, the higher the activity of reducing acetylene to ethylene. Also found that the system’s alkalinity has a significant impact on the synthesis results.
