Low Temperature (4K) and High Pressure (6.5 Kbars) Crystal Structures of (TMTSF)2PF6

Abstract
We have performed structural investigation of the (TMTSF)2PF6 salt at low temperature (neutron diffraction) and under pressure (X. Ray diffraction). Evolutions of the main structural parameters are described. Their descriptions allow the first structural approach of pressure effects on the Bech-gaard salts and give comparative informations for a same compound.
