Abstract
The temperature and pressure dependence of the electrical conductivity of the alpha'-(BEDT-TTF)(2)Ag(CN)(2) salt shows a transition between two semiconducting phases at a critical temperature depending on press ure. This transition is crystallographically characterized by the appe arance of a superstructure corresponding to the doubling of the b para meter. We present and discuss here the parameters evolution at decreas ing temperature and increasing pressure and the structural evolution u nder constraints.
