(CNB-EDT-TTF)6Ag∼7.91I∼9.15 (CNB-EDT-TTF = 5-cyanobenzene-ethylenedithio-tetrathiafulvalene) is reported as the first bilayer conducting salt with a polymeric anion. The anion is a silver-deficient iodoargentate layered polymer with a composition close to Ag7.95I9.19, as deduced from single crystal X-ray diffraction. In spite of disorder in the silver iodide polyanion layer, and the large unit cell with six inequivalent donor molecules, this compound presents clear metallic properties down to 1.5 K, comparable to those of the β′′-type 4:1 salts of this donor with small discrete anions, with room temperature electrical conductivity in the range of 3–10 S/cm and thermoelectric power of ∼100 μV/K.
