Synthesis and properties of bridged phthalocyaninatoiron(II) complexes with bidentate aliphatic isocyanides

Phthalocyaninatoiron(II) (PcFe) was reacted with several aliphatic 5, 10–13, alicyclic 14, and aromatic isocyanides 3, 4 to form monomeric 15–17 and bridged oligomeric complexes 18–22. The syntheses of the isocyanides from the corresponding amines are described. All the products were characterized by spectroscopic methods. The coordination behaviour of the isocyanides based on their spectroscopic properties is discussed. The oligomers 18–22 show conductivities in the low semiconducting region, but by doping with iodine conductivities between 10−5 and 10−2 S/cm were obtained.
