在乙腈体系中合成了Fe(Ⅱ)的配合物[Fe(phon)3](ClO3)2.2CH3CN(phon=1,10-邻菲咯啉-5,6-二酮)。X-射线衍射单晶结构表明:配合物[Fe(phon)3](ClO3)2.2CH3CN属于正交晶系,P212121空间群,Fe(Ⅱ)与3个phon配体的6个氮原子配位,形成变形的八面体结构。配合物[Fe(phon)3](ClO3)2.2CH3CN中的氢键和C=O…π相互作用将配合物连接成二维网络结构。用红外光谱、紫外-可见光谱对配合物[Fe(phon)3](ClO3)2.2CH3CN进行了表征,并用紫外光谱法对配合物与ct-DNA的相互作用做了初步研究,结果表明配合物与ct-DNA的结合常数(Kb)为2.2×105L.mol-1。
The complex of Fe (Ⅱ) [Fe (phon) 3] (ClO3) 2.2CH3CN (phon = 1,10-phenanthroline-5,6-dione) was synthesized in acetonitrile system. The crystal structure of X-ray diffraction showed that the complex [Fe (phon) 3] (ClO3) 2.2CH3CN belongs to the orthorhombic system and P212121 space group. Fe (Ⅱ) coordinates with the six nitrogen atoms of the three phon ligands , Forming a deformed octahedral structure. Complexes [Fe (phon) 3] (ClO3) 2.2CH3CN in the hydrogen bond and C = O ... π interaction complexes will be connected into two-dimensional network structure. The complex [Fe (phon) 3] (ClO3) 2.2CH3CN was characterized by IR and UV-Vis spectra. The interaction between the complex and ct-DNA was studied by UV spectroscopy. The results showed that the complex The binding constant (Kb) to ct-DNA was 2.2 × 10 5 L · mol -1.
