Abstract
Unsymmetrical dioxime ligand and its mono- and multinuclear metal complexes were synthesized and characterized by 1H and 13C NMR spectra, FT-IR, UV-Vis, elemental analysis, melting point measurements, LC-MS spectroscopy, molar conductivity measurements and magnetic susceptibility and cyclic voltammetry techniques. We firstly prepared new unsymmetrical dioxime ligand (1) and its mononuclear [Ni(dioxime)2] complex (2). Then, the intramolecular O-H⋯O bridges are replaced with Cu(II)(N-N) complex to synthesize multinuclear [Ni(dioxime)2Cu2(N-N) 2](ClO4)2 oxime complexes (3-7) where N-N = 2,2′-bipyridine (bpy), 1,10-phenanthroline (phen), 3,3′-dicarboxy-2, 2′-bipyridine (dcbpy), 4,5-diazafluoren-9-one (dafo) and 1,10-phenanthroline-5,6-dione (dione). The mononuclear complex [Ni(dioxime) 2] (2) was used as a precursor for building multinuclear oxime complexes (3-7). In this paper, our goal is to study spectroscopic, electrochemical and catalytic properties of this new ligand and its metal complexes.
