New bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF)-, bis(ethylenediseleno)tetrathiafulvalene (BEST)- and bis(ethylenedithio)tetraselenafulvalene (BETS)-based organic charge-transfer (CT) salts&mdash, &alpha, (BEDT-TTF)3(HOC2H4SO3)2 (1), &beta, (BEST)3(HOC2H4SO3)2·, H2O (2) and &alpha, (BETS)2(HOC2H4SO3)·, H2O (3)&mdash, have been prepared. Salts 1 and 2 show semiconducting behaviour. Salt 3, which is almost isostructural to &alpha, (BETS)2I3, shows metallic behaviour down to 70 K and then shows a broader metal&ndash, insulator transition than that of &alpha, (BETS)2I3. The reason for the difference in behaviour is estimated by the comparison of the Madelung energies of the full set of patterns of possible donor&rsquo, s charge-ordered and anion&rsquo, s disordered states.
