High Conductivity of the New Supramoleclar Copper Complex with Oxidized Pyrazinoselenathiafulvalene (=pyra-STF) as the Ligand, [(CuCl1.5)-Cl-I(pyra-STF)(0.5+)]
A new supramolecular copper complex with pyrazinoselenathiafulvalene (=pyra-STF) as the ligand, [CuCI1.5(pyra-STF)], has been synthesized. This complex forms a peculiar crystal structure; Cu-I and Cl- construct 1D supramolecular chains with coordination of the oxidized donor molecules, pyra-STF0.5+, as ligands. The pseudo-1D donor-ligand columns afford high conductivity, 25 S cm(-1), at 298 K and are prohibited to be a complete singlet state below 190 K by the linked, rigid 1D [CuCl1.5](n) chains.
