Abstract
Conductivity and permittivity of the quasi-one-dimensionsional organic tran sfer salt (TMTTF)(2)PF6 have been measured at low frequencies (10(3)-10(7) Hz) between room temperature down to below the temperature of transition in to the spin-Peierls state. We interpret the huge real part of the dielectri c permittivity (up to 10(6)) in the localized state as the realization in t his compound of a charge ordered state of Wigner crystal type due to long-r ange Coulomb interaction.
