Covalent linking of C 60 to electron donors is expected to create attractive substrates for the study of electron or energy transfer. The successful synthesis of a 4,5‐dimethoxy‐ o ‐quinodimethane‐C 60 adduct is described. The unique crystal structure has been determined and the bandgap measured by ESCA. One of the most interesting features of the crystal structure of the mono‐adduct is the close contact of one of the methoxy groups to a neighboring C 60 , leading to the formation of a chain of interacting fullerene cages.
