Bis(ethylenedithio)tetrathiafulvalene Radical Salts with Anderson Type Heteropolymolybdates Containing Tris(alkoxo) Ligands

Anderson type heteropolymolybdates containing tris(alkoxo) ligands {MnMo6O18[(OCH2)3CR]2}3- (R = −CH2OH, −CH2CH3, and −NH2) have been successfully utilized as anions to generate the bis(ethylenedithio)tetrathiafulvalene (ET) radical cation salts: (ET)5{MnMo6O18[(OCH2)3CCH2OH]2} (5H2O) 1, (ET)5{MnMo6O18[(OCH2)3CCH2CH3]2}·(2CH3CN) 2, and (ET)6{MnMo6O18[(OCH2)3CNH2]2}·(2CH2Cl2) 3. Compound 1 shows a metallic conducting property, but compound 2 presents semiconducting behavior although both compounds possess β‘ ‘ phase packing of ET molecules, while ET molecules in compound 3 exhibit α‘‘‘ phase packing.
