摘要：

Air stable bulk single crystals of(P(C6H5)(4))(2)C60I Can be grown by electrocrystallisation. We will prove that this salt is an excellent model system for the ferromagnetic [TDAE]C-60 and furthermore a good tool, to study the dynamics of C-60 mono anions in the solid state. We could directly observe the temperature dependence of the Jahn-Teller distortion of the C-60(-) and the transition from a static to a dynamic Jahn-Teller distortion at about 140 K. We will present detailed EPR linewidth and g-factor measurements at 9.7 and 34 GHz between 3.5 and 300 K.
