Abstract

The reaction of the redox active 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene (dppBIAN) and iron(II) iodide in acetonitrile led to a new complex [(dpp-BIAN)FeII I2 ] (1). Molecular structure of 1 was determined by the single crystal X-ray diffraction analysis. The spin state of the iron cation in complex 1 at room temperature and the magnetic behavior of 1 in the temperature range of 2–300 K were studied using Mossbauer spectroscopy and magnetic susceptibility measurements, respectively. The neutral character of dpp-BIAN in 1 was confirmed by IR and UV spectroscopy. The electrochemistry of 1 was studied in solution and solid state using cyclic voltammetry. The generation of the radical anion form of the dpp-BIAN ligand upon reduction of 1 in a CH2 Cl2 solution was monitored by EPR spectroscopy.
