Bis(ethylenedithio)tetrathiafulvalene radical salts with Anderson type heteropolymolybdates containing tris(alkoxo) ligands

Anderson type heteropolymolybdates containing tris(alkoxo) ligands {MnMo6O18[(OCH2)(3)CR](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)(3)CCH2OH](2)} (5H(2)O) 1, (ET)(5){MnMo6O18[(OCH2)(3)CCH2CH3](2)}center dot(2CH(3)CN) 2, and (ET)(6){MnMo6O18[(OCH2)(3)CNH2](2)}center dot(2CH(2)Cl(2)) 3. Compound 1 shows a metallic conducting property, but compound 2 presents semiconducting behavior although both compounds possess beta '' phase packing of ET molecules, while ET molecules in compound 3 exhibit alpha'''. phase packing.
