Abstract: Transition metal-sulfur complexes have attracted much attention because of their resemblance to the active sites of redox metalloenzymes and their potential applications to homogeneous catalysis. The crystal structure of nitrogenase reveals that the active center of the enzyme contains a Fe-Mo-S cluster. However, the mechanism by which the N-N triple bond of nitrogen is activated in the Fe-Mo-S active center remains unclear. Owing to the periodic relationship between Fe and Ru, one may expect that the more subsitutionally inert Ru-sulfur complexes may serve as structural and functional models for Fe-S enzymes. Additionally there is an increasing interest in Ru-S complexes because they are found to be better hydrodesulfurization catalysts than the commercial Mo-S systems. We here describe the synthesis and crystal structures of some ruthenium complexes of bis(diphenylthiophosphosphoryl)amide (L).
