Abstract
Metallaheteroborane clusters containing group-16 elements as cluster constituents were initially of interest solely for the synthesis of high-nuclearity clusters. However, owing to recent developments in their chemistry towards hydrogenation and isomerization of olefins, nido to closo dehydrogenation of clusters, the development of new and improved routes for the synthesis of novel metallaheteroborane clusters have become of interest. In recent years, the chemistry of metallaheteroboranes, with chalcogen(s) as the heteroatom(s), has noted significant growth both in terms of synthetic methodology as well as the advent of unique frameworks ranging from polyhedral cages and macropolyhedral clusters to triple-decker sandwich complexes and hydrocarbon-mimics like cubanes and homocubanes. This review provides a brief account of the syntheses of diverse structural motifs adopted by the metallachalcogenaborane clusters; their electron counts along with latest advances in their chemistry.
