Abstract in another language

We used single crystals of A+(C6H5)42C60−·B− as an ideal model system to determine accurately principal values and principal axes of the g-tensor of the \{C60\} mono radical anion embeded in a crystal field. The experimentally observed non axial g-tensor which corresponds to the molecular Jahn–Teller distortion of C60− shows that the crystal field has stabilized the Jahn–Teller distortion of \{D2h\} symmetry along a specific molecular \{C2\} axis. These stabilization occurs below a characteristic temperature Ts for two C60−· orientations (merohedral disorder) and depends on the cations as we could show by the substitution of P+ for As+.
