Abstract
The alpha-(BETS)(2)Cu5I6 radical cation salt was obtained by electrocrystal lization and its crystal structure has been determined by single crystal X- ray diffraction. The salt has a layered crystal structure and shows an unus ual two dimensional polymeric anionic network. Crystal resistance and optic al properties were studied. At ambient pressure the electrical conductivity of this salt shows metallic behaviour down to 25-30 K and then an M-I tran sition takes place. It was found this transition was completely suppressed at pressures above ca. 10 kbar. After release of pressure the salt shows me tallic behaviour down to 1.3 K.
