Polyhedral Metallaboranes and Metallacarboranes

This chapter deals with metallaborane, metallacarborane and some unique metallaheteroborane clusters covering the years from 2005 to early 2021. Single cage polyhedra, starting from small 4-vertex clusters to large 16-vertex clusters are discussed. Apart from single cage clusters, many condensed clusters have also been discussed. This chapter describes the syntheses, characterizations, structural features, electron counts, and reactivities of these polyhedral molecules.
