Novel phthalocyanine conductor containing two-dimensional Pc stacks, [PXX](2)[Co(Pc)(CN)(2)] (PXX=peri-xanthenoxanthene, Co(Pc)(CN)(2)=dicyano(phthalocyaninato)cobalt(III))
A novel phthalocyanine conductor containing 2-D pi-pi stacks of the partially oxidized Co(Pc)(CN)(2) units has been obtained by the electrochemical oxidation method with PXX. The crystal is highly conductive (> 10(3) S cm(-1)) at all the temperatures measured (5 K < T < 300 K). Though the metallic character becomes clearer compared with the single chain or ladder chain conductors, the 2-D sheet has been found to be still anisotropic.
