摘要：

We have prepared the cation radical salts based on a nonplanar donor 4,11-bis(4',5'-ethylenedithio-1',3'-dithiole-2'-ylidene)-4,11-dihydroanthra[2,3-c][1,2,5] thiadiazole (BEDT-ATD), (BEDT-ATD)(2)X(Solvent) (X=PF6, BF4; Solvent=THF, DHF (2,5-dihydrofuran)). The band structure of a stable organic metal (BEDT-ATD)(2)PF6(THF) is presented. The replacement of an anion or a solvent molecule has induced a metal-insulator transition at 200 K and 150 K for(BEDT-ATD)(2)BF4(THF) and (BEDT-ATD)(2)PF6(DHF), respectively.
