Abstract

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 I3-, 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.
