| Research Abstract |
Aiming at the reaction sites for conversion of nitrogen, transition metal-sulfur clusters were investigated as the models for the active site of nitrogenase, which was assembled from multiple metal and sulfur atoms. Stepwise synthetic routes were applied to construct the cluster skeletons, in which four metal and four sulfur atoms were located alternately at the corners of a cube. Reactivity of the cluster that could activate coordinated nitrogen molecule was revealed. Analogous clusters composed of different metal elements were prepared, and specific binding and conversion of hydrazine and carbon monoxide etc. on these clusters were achieved.
