NMR spectroscopy and single-crystal X-ray diffraction. All are of the form the 2,1,7-MC2B9-1′,7′-C2B10, and even though the structural studies reveal clear evidence of steric crowding between the arene or Cp/Cp* ligand on the metal and the pendant carborane cage, no isomerisation of the metallacarborane to either 2,1,8-MC2B9 or 2,1,12-MC2B9 occurs, even on heating to reflux in toluene.
