The Raman spectra of the neutral state complex C<SUB>60</SUB>*C<SUB>10</SUB>H<SUB>12</SUB>Se<SUB>4</SUB> *2 (CS<SUB>2</SUB>) [C<SUB>10</SUB>H<SUB>12</SUB>Se4, tetramethyl-tetra-selenafulvalene (TMTSF) ] were measured as a function of pressure at room temperature. The pressure dependence of almost all intramolecular phonon modes exhibits irreversible changes at 5. 4 ± 0. 5 GPa, the more characteristic of them being the irreversible softening by 9 cm<SUP>-1</SUP> of the A<SUB>g</SUB> (2) pentagon-pinch (PP) mode, observed upon total pressure release. This softening is analogous to that observed in the case of KC<SUB>60</SUB>. These observations may be attributed to an irreversible phase transition involving the transfer of one electron from TMTSF donor to C<SUB>60</SUB> acceptor molecule.
