Exploring the interactions of d-block elements with boron. A case for electronically unsaturated metallaborane clusters

Abstract

The ability to synthesize metallaboranes of fixed cluster shape with varying numbers of metal atoms and metal identities highlights the unique ways in which the metals differ from their main-group counterparts in a cluster environment. Thus we have found that electronic unsaturation introduced by the use of early transition metals is expressed in an intriguing and novel manner in a metallaborane cluster.
