Abstract : Puzzled by the unusual conducting behavior of the as described (TMTSF)3Ta2F11 radical cation salt[1] (TMTSF = tetramethyl-tetraselenafulvalene) and the potential interest of the Ta2F11 monoanion in other molecular conductors, we have decided to revisit and extend the family of TTF radical cation salts containing this particular anion. During our investigation it turned out that the real anionic species was in fact the Ta2OF10 dianion. In this work we describe the structures, conductivity and band structure calculations of the (TMTXF)2Ta2OF10 hybrid salts (X = S or Se). We also present the new (DM-EDT-TTF)3Ta2OF10 materials based on the chiral donor dimethyl-ethylenedithio-tetrathiafulvalene (DM-EDT-TTF).
