Crystal structures and electrical properties of radical‐cation salts of the chiral organic donor TMET ( S , S , S , S ,‐bis‐(dimethylethylenedithio)tetrathiafulvalene) are described. Two structural types, 2:1 with octahedral anions Pf − 6 , AsF − 6 , SbF − 6 , I − 3(incommensurate), and 3:2 with tetrahedral anions BF − 4 , CIO − 4 , ReO − 4 are observed. Resistivity measurements between 2 and 298 K indicate that the 3:2 types are organic metals, while the other compounds are semiconductors. (TMET) 3 (CIO 4 ) 2 is metallic down to about 120 K at ambient pressure and remains metallic down to 2 K at 8 kbar.
