Spectral investigations of new organic conductors (BEDO-TTF)2(C3H2N3O3) and (DB-TTF) (C3H2N3O3) were performed. Optical absorption spectra in the range of 400-40 000 cm-1 of the powdered salts dispersed in KBr pellets were recorded and analysed. The spectra of (BEDO-TTF)2(C3H2N3O3) are characteristic of organic metals and show small anisotropy, which is typical of quasi-two-dimensional materials. On the other hand, the spectra of (DB-TTF)(C3H2N3O3) are typical of semiconducting materials. The (BEDO -TTF)2(C3H2N3O3) salt undergoes a phase transition at about 120 K. The polarized reflectance spectra of single crystals of (BEDO-TTF)2(C3H2N3O3) were recorded in the range of 600-7000 cm-1, down to 4 K. The frequency dependences of reflectivity were fitted with a Drude model and the transport parameters were evaluated and investigated vs. temperature. An assignment of some vibrational bands in the IR spectra was proposed.
