Studying gold compounds analytically and spectroscopically using novel diamine donor ligands

Abstract

Whenever N-(Naphthylethylenediaminedihydrochloride) and 4-nitroaniline were combined, they yielded N-(2-Amino-5-nitrophenyl) diazenyl ethyl)-naphthalen-1-amine, an azo-ligand. We started with the primary compound: Azo, and then we added salts of sodium pyrophosphate, organic acids like malonic acid, and other secondary ligands like oxalic acid. Researchers conducted thorough analyses of the materials' spectroscopic (UV-Vis and FTIR), (molar conductivity), and magnetic properties (Ultraviolet-Vis and FTIR). The infrared spectrum and molar conductivity data show that all of the complexes are electrolytic, and the bidentate ligands are all coordinated to gold (III). Based on data from magnetic susceptibility, mass spectrometry, elemental analysis, 1H-NMR, and UV-Vis spectra, the compounds were shown to have square planar geometries.
