Synthesis, characterization and solvatochromism studies of two new mixed-chelate copper(II) complexes containing β-ketoamine and diamine ligands

Two mixed-chelated copper(II) complexes with diamine and β-ketoamine were prepared. The complexes are soluble in organic solvents and present solvatochromism. Their solvatochromism was examined using an MLR computational method. The solvatochromic behaviors of the complexes are based on the DN value of the solvent.
