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-])Cl2]. It is observed that [Ru^[III](Pc^[2-])Cl2] 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.Hindawi Publishing Corporation2013engjournal articleVoRhttp://hdl.handle.net/2115/51038https://doi.org/10.1155/2013/4863182090-9063Journal of Chemistry2013486318https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/51038/1/JoC2013_486318.pdfapplication/pdf776.26 KB2013
