Solvatochromism Study on the Copper(II) Complexes Containing 3–Substituted Derivatives of Acetylacetonate Ligands

Solvatochromic properties of a series of bis(3–substituted derivatives of acetylacetone)copper(II) (X-acacH , X = Cl, H. CH ) complexes were studied. All the complexes demonstrated negative 3 solvatochromism.Among the complexes the Cu(Cl-acac) , demonstrated the most solvatochromism. A multi-parametric equation 2has been utilized to explain the solvent effect on the d-d transition of the complexes using SPSS/PC software.The stepwise multiple linear regression (SMLR) method demonstrated that the donor power of the solvent plays the most important role in the solvatochromism of the compounds
