Abstract

Using three different BETS variants (BPT-TSF 2, EDT-PT-TSF 3, and BEST-TSF 4), six new radical cation salts of D2·MX4-type are prepared. The β-type salts with FeCl4- anion obtained from the donors 2 and 3 are isostructural with the corresponding BETS salts. From the donor 3, a radical salt with β-type donor packing is obtained with GaCl4 anion. All these salts from donors 2 and 3 are metallic down to low temperature. On the other hand, the donor 4 possessing selenium atoms in outer heterocycles gives two λ-type salts. They are highly conductive at room temperature, but not metallic at low temperature range.
