近年来铁卟啉的结构研究及其应用发展很快。X-射线分析、穆斯鲍尔能谱及共振拉曼光谱等的研究表明,轴向配位的高铁卟啉呈高自旋结构时,铁原子位于四个氮原子组成的平面外成四方单锥构型;呈低自旋结构时,铁原子与四个氮原子成四方平面构型,见图1、2。由于金属卟啉轴向配合物结构的复杂性以及准确地归属红外谱带的困难,高铁卟啉轴向配合物的红外光谱近年才有人开始进行研究。本文对比考查Fe(PPⅨ)Cl、Fe(TPP)Cl、〔Fe(PPⅨ)(Py)〕Cl和
In recent years, the structure of iron porphyrin research and its application developed rapidly. X-ray analysis, Murs Bauer spectroscopy and resonance Raman spectroscopy studies have shown that the axial coordination of the high-iron porphyrin was high spin structure, the iron atoms located in the four nitrogen atoms out of plane into a quadrangular cone structure Type; low-spin structure, the iron atoms and four nitrogen atoms into a square planar configuration, shown in Figure 1,2. Due to the complexity of the metalloporphyrin axial complex structure and the difficulty of accurately assigning the infrared band, the infrared spectrum of the axial complex of the high-iron porphyrin has been studied in recent years. In this paper, we compare the Fe (PPIX) Cl, Fe (TPP) Cl, [Fe (PPIX) (Py)] Cl and
