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.
