Overview and Perspective on Metalloid Tin Cluster Chemistry
Abstract
Since the initial discovery of the first metalloid tin cluster by Wiberg in 1999 the number of isolated and characterized compounds is still low. However, numerous theoretical calculations indicate a large variety of compounds yet to be discovered. The calculations thereby indicate that larger clusters might form a cluster of clusters arrangement rather than compact structures. This trend seems to be supported by the largest metalloid tin clusters exhibiting up to 20 tin atoms. In this perspective, recent results and future possibilities of this fascinating class of metalloid tin cluster compounds are discussed.
