Ⅰ. INTRODUCTION The structure of the active center in nitrogenase and the synthesis of a model compound are interesting subjects for many chemists. It is considered that the structure of the active center in nitrogenase can be a structure of Mo—Fe—S cluster compound. And two distinct models were proposed for the active center structure of nitrogenase. After that, the Mo—Fe—S cluster complexes with the active sites of the model nitrogenase have
