| Research Abstract |
The elevated intrest that has recently emerged in d-pi electron systems of bimetallic complexes containing a pi-bond spacer is owed to their unusual electronic, optical, and magnetic properties. A systematic limitation for all the pi-electron systems in these compounds is the restriction to 2nd row elements. The chemistry of pi-electron systems containing heavier main group elements has recently received much attention even though they are known to be highly reactive. In this research project, we have developed a new bulky ferrocenyl unit as d-electron unit for the stabilization of such pi-bonds of heavier main group elements. Then, we have successfully applied it toward the synthesis of novel d-pi-electron systems containing heavier main group elements. A series of 1,2-bis(ferrocenyl)dipnictenes with a Pn=Pn(Pn=P,Sb,Bi) pi-spacer. The systematic comparison of their structural parameters and physical properties allowed us to recognize they should be unique d-pi electron systems.
