Abstract: New applications in which the carborane and metallacarborane
species play a crucial role have been recently developed. In these applications,
clusters display many particular characteristics that do not find parallel
in their organic counterparts. The o-carborane can modulate the
C���C distances depending on the substituents bonded to the cluster
carbon atom and can lead to the formation of uncommon halogenophosphane
charge-transfer �spoke � complexes with iodine due to their electron-withdrawing
capacity. Besides, metallacarboranes have been used as doping agents
in organic conducting polymers and as catalysts in Kharasch reactions.
