Abstract：
The reaction of the redox active 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene (dpp-BIAN) and iron(II) iodide in acetonitrile led to a new complex [(dpp-BIAN)FeIII2] (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 CH2Cl2 solution was monitored by EPR spectroscopy.
摘要：
氧化还原活性的1,2-双[（2,6-二异丙基苯基）亚氨基]萘（dpp-BIAN）与碘化铁（II）在乙腈中的反应产生了新的络合物[（dpp-BIAN）FeIII2]（1）。通过单晶X射线衍射分析确定1的分子结构。使用穆斯堡尔谱和磁化率测量研究了室温下配合物1中铁阳离子的自旋状态和1在2-300K温度范围内的磁行为，分别。通过红外光谱和紫外光谱证实了dpp-BIAN在1中的中性特性。用循环伏安法在溶液和固体状态下研究了1的电化学。通过EPR光谱法监测在CH2Cl2溶液中还原1时dpp-BIAN配体的自由基阴离子形式的产生。
