Analytical and spectroscopic study of copper compounds with diamine donor new ligands

Naphthylenediamine dihydrochloride and 4-nitroaniline were utilized to make N-(1-Naphthylethylenediamine dihydrochloride) naphthalen-1-amine, an azo ligand, in this case. It was possible to synthesize four new Cu (II) complexes by using four different compounds, including the primary ligand azo, as well as the secondarily used sodium-pyriphosphate-oxalic- and malonic-acid-based secondary ligands. Spectroscopy (UV-Vis, FTIR, mass, 1H-NMR spectra; atomic absorption; elemental analysis); magnetics; and molar conductivity were all used to thoroughly evaluate the produced substances. They found that all of the complexes were non-electrolytic and that all of the bivalent ligands were in coordination with copper (II) using infrared spectrum and molar conductivity data. Tetrahedral geometry of the complexes was discovered through the use of magnetic susceptibility measurements, mass spectrometric data, elemental analysis, H-NMR data, and ultraviolet visible spectra
