Abstract
The infrared reflectivity, the temperature-dependent conductivity, and thermopower of the one-dimensional conductor [Pt] · 2O, LiPt(mnt), is presented. It undergoes a simple Peierls transition at K, which is not influenced by correlations or by cation ordering. The metallic LiPt(mnt) is characterized by a transfer integral eV. When it behaves as an intrinsic Peierls semiconductor with meV. At lower temperatures the thermopower indicates extrinsic behavior due to the presence of donor impurities. Our results agree with those obtained from magnetic-susceptibility studies.
