Organic conductor θ-(BEDT-TTF)Cd1.38I3 with layered perovskite-like structure

详细

The organic conductor θ-(BEDT-TTF)Cd_1.38I₃ (1) (BEDT-TTF is bis(ethylenedithio)- tetrathiafulvalene) with layered perovskite-like structure was synthesized. In the crystal structure of 1, θ-type organic conducting layers, which are built up from BEDT-TTF stacks, alternate with inorganic insulating layers. The latter are composed of CdI₆ octahedra and CdI4 tetrahedra linked together to form a two-dimensional anionic network. Measurements of the temperature dependence of the electrical resistance demonstrated that compound 1 is a semiconductor.
