ResumoThe synthesis, structures and physical characterizations of the first radical ion salts of the organic donor BET-TTF1 with polyoxometalate clusters ([M6O19 ]2– ; M=WVI , MoVI , 2) are reported. The 2:1 salts (BET-TTF+)2 [M6O19 ]2– are formed by pairs of the BET-TTF+ radical cations surrounded by polyanions so as to form a 3D packing of anions and cations with short intermolecular contacts between the cation pairs. The synthesis, physical properties and main structural features of the first radical ion salts of the organic donor BET-TTF 1 with the polyoxometalate cluster [SiW12O40 ]4–3 are also reported. The 4:1 salt (BET-TTF+)4 [SiW12O40 ]4– is formed by a 2D hexagonal packing of anions and by isolated BET-TTF+ pairs. The compounds are insulators and diamagnetic.
