Two unique polymeric-anion derivatives of BEDT-TTF have been synthesized and characterized by single crystal x-ray diffraction, electrical properties measurements, and band electronic structure calculations. They are (BEDT-TTF)Ag/sub 4/(CN)/sub 5/, 1, and (BEDT-TTF)/sub 3/Ag/sub x/I/sub 8/ (x approx. = 6.4), 2. I contains the first three-dimensional radical-cation donor-molecule network found in an organic conductor and a novel (Ag/sub 4/(CN)/sub 5/)/sup -/ polymeric anion. 2 is the first organic metal-solid electrolyte hybrid and contains alternating layers of BEDT-TTF donor-molecule networks and polymeric silver iodide anions. In the latter, the silver ions are disordered over numerous, partially occupied sites along one-dimensional channels. Both 1 and 2 exhibit metallic conduction at 300 K, but undergo phase transitions at low temperature. 11 refs., 3 figs.
