摘要

Three types of copper complexes as well as an oximate-bridged nickel complex with isonitrosoacetophenone 2-aminobenzoylhydrazone (H2L) have been prepared in ethanolic solution and characterized by elemental analyses, IR, H-1 NMR, UV-vis and magnetic susceptibility measurement. IR spectra show the ligand coordinates as a neutral, monoanionic and dianionic O,N,N-tridentate acylhydrazoneoxime ligand depending reaction conditions and metal salts employed. The elemental analyses results, spectroscopic and magnetic data are consistent with the formation of mononuclear copper complexes and binuclear complexes with both copper and nickel. The effects of varying pH and solvent on the absorption behavior of both ligand and complexes have been investigated. The extraction ability of acylhydrazoneoxime ligand has been examined by the liquid-liquid extraction of selected transition metal [Cu2+, Ni2+, CO2+, Cr3+, Hg2+, Zn2+, Cd2+ and Mn2+] cations. The ligand shows strong binding ability toward copper(II) ion. (c) 2006 Elsevier B.V. All rights reserved.
