We have produced the fullerene dimers C(120), C(120)O, and C(120)O(2) by a high-speed vibration milling technique. The thermal stability of C(120), C(120)O, and C(120)O(2) has been studied in the temperature range 150-350 degrees C for up to 4 h under vacuum. The bridging oxygen atoms were found to substantially increase the stability of the fullerene dimer molecules.
