摘要: 本文研究了一种新的钼原子含端氧配位的Mo-Fe-S原子簇络合物[Et4N]3·[Mo2FeS8O2]·CH3CN(Ⅰ)的合成、性质和结构,与[Et4N]3[Mo2FeS8O2](Ⅱ)和[Bu4N]3[Mo2FeS8O](Ⅲ)对比得出:(1)三种络合物得电子能力的顺序为:Ⅰ<Ⅱ<Ⅲ.(2)它们在空气中的稳定性顺序为:Ⅰ>Ⅱ>Ⅲ.(3)它们的分子对称性强弱的顺序为:Ⅱ>Ⅰ>Ⅲ.(4)催化乙炔还原为乙烯的活性顺序与它们的稳定性正相反.

Abstract: Tn this paper, synthesis, structure and properties of a new Mo-Fc-Scluster complex (Et4N)3(Mo2FeS8O2)·CH3CN (Ⅰ) with oxygen coordinated to Mo atom are reported, in which UV-Vis. spectra, IRspectra, Mossbauer spectra, eletrochemical properties and catalytic activity reducing C2H3 to C2H4 are involved. Our conclusions obtained from contrasting properties of the complex with that of the complex (Et4N)3(Mo2FeS8O3) (Ⅱ) and (Bu4N)3(Mo2FeS8O) (Ⅲ) previously reported by us are as follows (1) the electrochemical data show that the order of ability for obtaining electron is Ⅰ<Ⅱ<Ⅲ, (2) the order of stability in air is Ⅰ > Ⅱ>Ⅲ, (3) the order of symmetry is Ⅱ>Ⅰ > Ⅲ, (4) the order of reducing C2H3 to C2H4 by catalysis is contrary to that of stability.
