Abstract

The study of organic donor-inorganic cluster hybrids has been extended to polyoxometalates with higher nuclearities and different shapes using the heteropolyanion [P2W18O62]6⊖ combined with bis(ethylenedithio)tetrathiafulvalene. The resulting hybrid material is unique in several respects: the new radical salt has an unprecedented stoichiometry and β-type packing; it is the first well-characterized radical salt of a polymetalate to exhibit metallic behavior. Further possibilities for investigation are briefly outlined.
