Abstract

Pseudo first-order reaction conditions of excess Cu(II) and Ni(II) (dehydroacetato) Hdha, complexes concentration over second ligands such as 8-hydroxyquinoline (Hquin) or 1,4-dihydroxyanthraquinone (H₂dhaq) was employed. The ligand substitution reactions of (dha) in Cu(II) and Ni(II) complexes with 8-hydroxyquinoline or 1,4-dihydroxyanthraquinone were investigated spectrophotometrically in nonpolar solvents like cyclohexane, chloroform and dichloromethane. The reaction was performed at four different temperatures (283, 288, 293 and 298 K). The observed rate constant (k_obs) depends on the concentration of both leaving and entering ligands. The higher values of jobs are associated with a lower activation energy, i.e. the entropy is greater for the slower reaction. The solid mixed ligand complexes were isolated and characterized by elemental analysis, magnetic moments, FT-IR, ESR, molar conductivity and UV-visible spectral techniques. Square planar geometries of Cu(II) complexes and distorted octahedral for the Ni(II) complexes are suggested.
