Abstract (Benzophenone)9(KI)2I7, CHCl3 single crystals have a golden metallic reflection on the surfaces parallel to the polyiodine chain axis. The compound is a member of a large class of channel-like inclusion compounds in which isolated iodine atom chains are the only possible conducting strands in an otherwise insulating matrix. The (contactless) microwave conductivity is ～ 10 Ω?1 cm?1 at room temperature with an activation energy of ～0.03 eV down to 70°K, while the dc conductivity is ～10?-6. Conductivity is strongly frequency dependent and contact problems are severe. |
