The synthesis, crystal structure and spectroscopic properties of the hybrid radical cation salt containing oxidized o-3,4-dimethyltetrathiafulvalene (o-Me2TTF) and the Lindquist polyoxometalate anion [W6O19](2-) are reported. The title salt represents the first time a Lindquist polyoxometalate has been utilized as the counter anion with this unsymmetrical member of the TTF family of derivatives. The salt crystallizes in the triclinic space group with a = 7.6211(7) , b = 9.5231(9) , c = 12.2148(11) , alpha = 105.5870(10)A degrees, beta = 106.8340(10)A degrees and gamma = 95.6950(10)A degrees. Resolution of the solid state structure revealed that the o-Me2TTF radical cations aggregate as isolated face-to-face dimers with intradimer interactions between neighboring sulfur atoms at distances < 3.6 . Hydrogen bonding was also observed between hydrogen atoms bound to sp (2)-hybridized carbon atoms of o-Me2TTF and bridging oxygen atoms of [W6O19](2-). Single crystal IR and Raman spectra were also collected and provide further evidence that the o-Me2TTF donors have been oxidized to their corresponding radical cationic states.
