Abstract :
We report a far-infrared vibrational study of (Ph4P)2IC60 which reveals a room temperature Jahn-Teller distortion of the C60 monoanion to either a D5d or D3d reduced-symmetry point group. Temperature dependences of the intramolecular C60 and counterion vibrations indicate a weak phase transition of the bulk material occurring between 125 and 150 K.
