Pressure-induced structural phase transition in the Bechgaard-Fabre salts

By A. Pashkin, M. Dressel, S. G. Ebbinghaus, M. Hanfland and C. A. Kuntscher


The crystal structures of the quasi-one-dimensional organic salts (TMTTF)$_2$PF$_6$ and (TMTSF)$_2$PF$_6$ were studied by pressure-dependent x-ray diffraction up to 10 GPa at room temperature. The unit-cell parameters exhibit a clear anomaly due to a structural phase transition at 8.5 and 5.5 GPa for (TMTTF)$_2$PF$_6$ and (TMTSF)$_2$PF$_6$, respectively
