摘要：
The title heterocycle-fused tetraselenafulvalene derivative, ET-TSF (ethylenethiotetraselenafulvalene) has been synthesized as a novel electron donor. Electrocrystallization of ET-TSF gave highly conductive radical cation salts with I-3(-), Cl-, Br-, and AuI2- counter anions. Among them, the AuI2 salt isostructural with the organic superconductor (MDT-TSF)-AuI2 (MDT-TSF methylenedithiotetraselenafulvalene) was highly conductive (1600 S cm(-1)) and metallic down to 1.8 K with no superconducting transition.
