The novel carborane mu-1,2-trimethylene-1,2-dicarba-closo-dodecaborane10 has been prepared and characterized. The carborane was found to undergo bas degradation to form the mu-1,2-trimethylene-3-1,2-dicarbadeca hydro-nido-undecaborate -1 ion which after deprotonation would react with transition metals to form several sandwich-bonded complexes of the type MnB9C5H152n-4 and C5H5MIIIB9C5H15. The formal nickel IV and cobaltIII complexes were found to undergo thermal rearrangements and the kinetics of the facile ligand isomerizations of NiB9C5H152 were determined using reverse current chronopotentiometry and visible spectroscopy.
