Two new methanofullerenes have been prepared by the reaction of C₆₀ with diazo substituted, potentially monoanionic, terdentate diamino aryl ligands, yielding a mixture of the open valence [5,6]- and closed valence [6,6]-isomers. Single isomers of the pure [6,6]-methanofullerenes were obtained by heating these mixtures in toluene solution.
