Two novel Schiff base ligands, 2,2'-((pentane-2,4-diylidene)bis(azanylylidene))bis(4-chlorophenol) and 2,2'-((pentane-2,4-diylidene)bis(azanylylidene))bis(4-methylphenol) were prepared by condensation reaction of acetylacetone with 2-amino-4-chlorophenol and 2-amino-4-methylphenol, respectively. Mononuclear Cu(II) complex of each ligand was also synthesized. These compounds were characterized by elemental analyses, inductively coupled plasma optical emission spectrometry, the Fourier transform infrared spectra, UV-Vis, molar conductivity, and magnetic susceptibility measurements. The ligands have been further characterized by ¹H- and ¹³C-NMR. The results suggest that the metal complexes of the ligands have a metal:ligand ratio of 1:1 and the Cu(II) ions are coordinated by the phenolic oxygen atoms and imine nitrogen atoms of the ligands. Moreover, the quantum chemical calculations of the compounds have been performed using the density functional theory. It has been found that the calculated spectroscopic values are in a good agreement with experimental data.
