New organic synthetic metals derived from BEDT-TTF, Ni(dsit) sub 2 and BEDO-TTF
Three strategies have been employed by us to synthesize new organic synthetic metals and superconductors. On the basis of structure-property correlations derived for the {beta}-(BEDT-TTF){sub 2}X salts, new charge transfer salts of BEDT-TTF with large, polarizable anions have been synthesized. The occurrence of molecular dimers has been engineered into salts of the new organic acceptor molecule, Ni(dsit){sub 2} (bis (4,5 -diselenolate -1,3-dithiole-2-thione) nickelate), to synthesize salts with acceptor packing similar to the donor packing in {kappa}-(BEDT-TTF){sub 2}Cu(SCN){sub 2}. Finally, two charge transfer salts of bis(ethylenedioxy)tetrathiafulvalene, BEDO-TTF, namely (BEDO-TTF){sub 2}AuBr{sub 2} and (BEDO-TTF){sub 2}AuI{sub 2} have been synthesized. The AuBr{sub 2}{sup -} salt, the first BEDO-TTF salt to be structurally characterized, is semiconducting below 263 K, while the AuI{sub 2}{sup -} salt shows metallic conductivity to low temperatures. 10 refs., 3 figs.
