Abstrakt: 1.By chemical and electrochemical methods we have obtained as single crystals two polymorphic modifications (ß and ß ') of the radical-cation salt of composition (BEDT-TTF)2IC12.2.We have studied the electrical conductivity, the thermoelectric and magnetic properties of both phases. We have found that theß phase is a metal (s293 - 200 ohm-1.cm-1) and the ß' phase is a semiconductor (s293 -= 10-2 ohm-1 · cm-1).3.We have established correlations between the structural and physical properties of ß- and ß'-(BEDT-TTF)2ICl2.
