High conductivity of the new supramolecular copper complex with oxidized pyrazinoselenathiafulvalene (=pyra-STF) as the ligand, [Cu(I)Cl(1.5)(pyra-STF)(0.5+)].
A new supramolecular copper complex with pyrazinoselenathiafulvalene (=pyra-STF) as the ligand, [CuCl(1.5)(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-STF(0.5+), 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 [CuCl(1.5)](n) chains.
