✦ Synopsis
Crystal structures and electrical properties of radical-cation salts of the chiral organic donor TMET (S.S,S,Sbis-(dimethylethylenedithio)tetrathiafulvalene) are described. Two structural types, 2:l with octahedral anions PF;, AsF;, SbF;, IT (incommensurate), and 3:2 with tetrahedral anions BF: , Cloy, ReO; 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),(CIO,), is metallic down to about 120 K at ambient pressure and remains metallic down to 2 K at 8 kbar.
