Partially-oxidized Iron(III) phthalocyanine (FeIIIPc) with axial CN or Br ligands are molecular conductors with giant negative magnetoresistance. Electron conduction occurs via intermolecular overlapping of Pc π-orbitals, while negative magnetoresistance is brought about by intramolecular interactio...
