CCB Colloquium presentation by Dr. Rhett Kempe, University of Bayreuth.
Host: Kai Hultzsch
Talk Title: "Some Progress in Metal-Metal Bonding"
Abstract: Chemical bonding is of fundamental interest and metal-metal bonding is receiving some attention in this regard. Two topics - polar metal-metal linkages and quintuple bonding - are discussed during the talk. First, recent progress in synthesising polar metal-metal bonds namely unsupported bonds between rare earth atoms (RE) and transition metals (TM) is discussed . Special focus is directed towards the use of such bond formation methodologies to generate highly reactive RE-TM clusters  (Figure below left). Secondly, recent progress in quintuple bonding is discussed  with a special focus on synthesising compounds with ultra-short metal-metal bonds  and understanding quintuple bonds by their reactivity  (Figure below right).
