These compounds are of substantial interest both inviewpoints of theory and practical applications, mainlyunder the stimulus to achieve synthetic models either foractive sites of iron-sulfur proteins or for transitionmetal catalysts. This thesis describes the synthesis, structures andconformations of 51 new iron-sulfur cluster complexes,which have been characterized by elemental analysis andstandard spectroscopic methods. In addition, single-crystalX-ray diffraction analyses were performed for 4 representa-tive new compounds. Reactivities of μ-〓 with mono- and di- Grig-nard reagents derived intermediates toward various organicelectrophilic substrates were studied, along with complexa-tion of arynyl-containing iron-sulfur clusters by 〓Thus, several bridged, non-bridged, monomeric, dimeric,homonuclear, heteronuclear iron-sullfur and iron-sulfur co-balt-carbon cluster complexes were synthesized. A novelreaction and convenient route for the synthesis in highyield of tetranuclear iron complexes 〓 containing atetracoordinated sulfur atom was discovered, whereas aplausible mechanism based on experimental results was propo-sed for the formation of the new cluster type.
