ABSTRACT
Solvatochromic properties of a series of bis(3–substituted derivatives of acetylacetone) copper(II) (X-acacH , X = Cl, H. CH3) complexes were studied. All the complexes demonstrated negative solvatochromism. Among the complexes the Cu(Cl-acac)2, demonstrated the most solvatochromism. A multi-parametric equation has 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.
