Preparation and physical properties of highly conducting metal (M = Ni, Co, Cu) coordination polymers

Abstract

Coordination polymers of nickel, cobalt and copper with the linking polydentate ligands tetrathiafulvalenetetrathiolate, benzene-1,2,4,5-tetrathiolate and phthalocyaninate have been prepared. The environmentally very stable materials have dc conductivities ranging between 10-2 S·cm-1 for the polyphthalocyaninato derivatives and 10² S·cm-1 for the tetrathiafulvalenetetrathiolates. The temperature dependence of the dc conductivity of the latter compounds is remarkably low.
