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. |
