Four mixed-chelate copper (II) complexes containing acetylacetonate ion and various diimine ligand were prepared and characterized by elemental analysis, spectroscopic and molar conductance measurements. These complexes are fairly soluble in various solvents and show positive solvatochromism. The ex
