This review systematizes data on the coordination ability of mono- and disubstituted derivatives boron cluster anions carboranes in complexation with transition metals. Boron clusters [BnHn]2–, monocarborane [CBnHn–1]–, dicarboranes [C2BnHn–2] (with non-functionalized carbon atoms) (n = 10, 12) containing B–X exo-polyhedral bonds (X N, O, S, Hal) are discussed. Synthesis structural features complexes known to date described. The effect complexing metal substituent attached cage composition structures final is analyzed. It has been established that substituted can act as both ligands counterions. A agent coordinate due three-center two-electron 3c2e MHB bonds, by functional groups, or a mixed type be realized, through BH groups substituent. As for B-substituted carboranes, coordinated substituents salts non-coordinated carborane have isolated; compounds bonding not characteristic carboranes.
