Abstract :
Electrocrystallization of ET in the presence of aromatic and aliphatic sulfonate anions has led to many new ET salts. These new ET based sulfonate complexes are characterized with use of x-ray diffraction, four-probe conductivity measurements, ESR and Raman spectroscopies. A new κ(4 × 4) donor packing motif was observed in (ET)2(C6H5CH2SO3)(H2O). Strong hydrogen bonding between the sulfonate anion S-O and the donor ethylene C-H provides the driving force for the ET salt formation. Many of these new sulfonate salts are highly conductive with some remaining metallic to ~ 4 K.
