Crystal structure of ruthenium phthalocyanine with diaxial monoatomic ligand: Bis(triphenylphosphine)iminium dichloro(phthalocyaninato(2-)) ruthenium(III)

Axially-ligated iron phthalocyanines have been found to be good molecular conductors with giant negative magnetoresistance (gnmr) which originates from a strong intramolecular π-d interaction between the metal and phthalocyanine. ab initio theoretical calculations showed that substitution of ruthenium into the phthalocyanine complex would result in a significant increase in the π-d interaction of the system,potentially intensifying gnmr. this paper presents the crystal preparation and x-ray structural characterization of bis(triphenylphosphine)iminium dichloro(phthalocyaninato(2-))ruthenium(iii),pnp [ru iii(pc 2-)cl 2]. it is observed that [ ru iii(pc 2-)cl 2] system has a symmetric planar rupc unit with perpendicular axial ligands which results in a unidirectional and uniform solid-state arrangement,suitable for π-d interaction-based molecular conductors with potentially exceptional gnmr. © 2013 derrick ethelbhert yu et al.
