Abstract:

The chemistry of metallacarboranes has witnessed an explosive growth since the first metallacarborane was reported in 1965. A large number of metallacarboranes of s-,p-, d-,and f-block elements are known; however, the highest hapticity of carboranyl ligands in these compounds has been six. We have recently discovered a brand new bonding mode for carborane molecules, and some recent findings in our laboratory will be presented in this paper.
