We report the room-temperature polarized infrared reflectance spectra of two radical cation salts based on halogenated TTF and two-dimensional polymeric iodoplumbate or Ag-doped iodoplumbate anions. These salts were ß-(EDT-TTF-I2)2(Pb5/6a1/6I2)3 and ß-(EDT-TTF-I2)2(Pb2/3+xAg1/3-2x??xI2)3, where x = 0.05 and a is a vacancy. Both materials display a metallic response, characteristic of quasi-onedimensional organic conductors. The ß-(EDT-TTF-I2)2(Pb2/3+xAg1/3-2x??xI2)3 salt, with x = 0.05 is partly transparent along the lowest conductivity direction in the infrared frequency range. The single-crystal polarized absorption spectrum recorded in this direction displays a number of vibrational features related to the intramolecular modes of the EDT-TTF-I2 molecule, which are assigned using available normal mode calculations. In addition, the absorption spectrum of the ß-(EDT-TTF-I2)2(Pb2/3+xAg1/3-2xaxI2)3 material dispersed in a KBr pellet is reported and discussed.
