The near-infrared absorption spectrum has been measured in [Pt(en)2][Pt(en)2Cl2](0104)4, (en)=ethylenediamine, irradiated with the 488 nm beam of an Ar-ion laser. In addition to the well-established intragap bands A around 1.6 eV and B around 2.0 eV, a broad band B’ is found to overlap the B band and be spread beyond 2.3 eV. No bands can be found at photon energies down to 1.2 eV below the A band. The results are discussed in relation to the �two-band� theory for polarons and solitons by Tinka-Gammel and coworkers (Phys. Rev. B45 (1992) 6435).
