The electron transport of Phthalocyanines (Pc) with central metal and di-axial ligands (such as Fe III (Pc)L2; where L = CN, Cl, Br) originates from its intermolecular Pc - orbital overlap while its giant negative magnetoresistance (GNMR) arises from its intramolecular Pc-(HOMO) and Fed (s=1/2) interaction. However, the -d interaction tends to localize itinerant electrons resulting in the decrease in the conductivity of the Fe III (Pc)L2 series compared to the non-magnetic Co III (Pc)L2 where -d interaction is absent. More so, the axial ligand field energy of the Fe III (Pc)L2 system is found to have the ability to proportionally modulate the -d interaction. In reference thereof, theoretical calculations point that isostructural Ru III (Pc)Br2 would provide the best balance of -d orbital energy interplay. That is, Ru III (Pc)Br2 is expected to be a molecule with high electrical conductivity and GNMR which would make it an ideal magnetic molecular conductor. This paper reports on the synthesis of Ru III (Pc)Br2.
