Experimental wet chemical approaches to complex an iron atom with two C60 fullerenes, representing a new molecule, dubbed a 'bucky dumbbell', have been demonstrated. The structure of this molecule has been determined by 13.C solid-state nuclear magnetic resonance (NMR) and electron paramagnetic spin resonance (EPR). Furthermore, this structure has been shown to have a unique binding site for dihydrogen molecules with the technique of temperature programmed desorption (TPD). The new adsorption site has a binding energy that is stronger than that observed for hydrogen physisorbed on planar graphite, but significantly weaker than a chemical C-H bond. These results indicate that further exploration of fullerene-based organometallic complexes could lead to a revolutionary discovery for onboard vehicular hydrogen storage.
