在对固氮酶固氮活性中心研究过程中,科学家们提出了各种活性中心的结构模型,这些理想模型多包含有MoFe_3S_3和MoFe_3S_4类立方烷簇骼,因此,这类模型化合物的合成自然地引起了许多化学家的重视。迄今,报道合成了这种MoFe_3S_4单立方烷化合物的在国外仅有Holm的研究小组,他们采用多步法通过断裂Mo—Fe—s双立方烷化合物得到了单立方烷原子簇,现在已经测定了四个这类化合物的晶体结构。
In the study of nitrogen fixation activity of nitrogenase, scientists proposed structural models of various active centers. These ideal models mostly contain MoFe 3 S 3 and MoFe 3 S 4 -bacubane clusters. Therefore, the synthesis of these model compounds naturally causes Many chemists value. To date, the only Holm-based research group that synthesized this MoFe 3 S 4 monovannane compound has reported the use of a multi-step method to obtain monovinylidene clusters by breaking Mo-Fe-s bis-cubic alkyl compounds The crystal structure of four such compounds.
