| Abstract: | In this paper we report the preparation, crystal structure and some physical properties of the conducting molecular (Perylene)2 [Pt(S4C4(CN)4)].The crystal structure consists of segregated stacks of perylene and Pt S4C4 (CN)4 units, with a spacing of 3.3 Å between the carbon atoms in the perylenes. The temperature dependence of the electrical conductivity is metallic with a maximum at approximately 15 K. At this temperature a sharp transition to an insulating state occurs. Magnetic suceptibility measurements confirm the existence of a transition in this temperature range. |
