摘要: 以三苯基膦(PPh3)为共配体,合成了2种新的铜(Ⅰ)和铜(Ⅱ)与菲啶(Phend)的配合物,其组成为[Cu(κ1-Phend)2Cl2](1)和[Cu2(κ1-Phend)2(κ1-PPh3)2(μ-Cl)2](2)。这些配合物的结构通过元素分析、摩尔电导率、FT-IR、UV-Vis和单晶X射线衍射进行了研究。典型配合物1的X射线衍射分析显示,Cu(Ⅱ)配位构型为扭曲的平面四方形,而双核配合物2的Cu(Ⅰ)中心为含μ-Cl-离子的不规则四面体构型。FT-IR谱、元素分析以及UV-Vis谱证实了它们的成分、几何形状和配体相互作用。2种配合物的结构通过密度泛函理论(DFT)计算进行了优化,以解释电子光谱特性。 |

Abstract: Two new complexes of copper(Ⅰ) and copper(Ⅱ) with phenanthridine (Phend) of the following composition:[Cu(κ1-Phend)2Cl2] (1) and[Cu2(κ1-Phend)2(κ1-PPh3)2(μ-Cl)2] (2) have been prepared in the presence of triphenylphosphine (PPh3) as a co-ligand. The structures of these complexes have been investigated by elemental analysis, molar conductivity, FT-IR, UV-Vis, and single-crystal X-ray diffraction. X-ray diffraction analysis of typical complex 1 reveals the distorted square planar geometry around copper(Ⅱ) whereas the binuclear complex 2 was irregular tetrahedral geometry around Cu (Ⅰ) center containing bridge Cl- ion. The FT-IR spectra, elemental analysis as well as UV-Vis spectra confirmed their components, geometries, and ligand interactions. The structures of both complexes have been optimized by density-functional theory (DFT) calculations to explain the electronic spectral properties. |
