Electrical conductivity studies of K1.75[Pt(CN)4]1.5H2O − K(def)CP.
Electrical conduction studies from the quasi-one-dimensional conductor K1.75[Pt(CN)41.5H2O, K(def)CP , show that this compound exhibits a new characteristic behaviour within the class of KCP-type conductors. At low temperatures the conduction is activated with a gap Δ=55meV (Eg=2Δ) , and at T-80 kelvin a transition to metallic state appears to take place. But the way in which the Peierls transition manifests itself differs from that of KCP. Above T=200 kelvin, the conductivity becomes strongly dependent upon temperature, which may be ascribed to the onset of free rotation of the crystal water.
