Synthesis, characterization and electrochemistry of copper(II), nickel(II), cobalt(II) and zinc(II) complexes of a binucleating ligand with [N2S]2O donors
摘要:
A heptadentate ligand (H3L) with a phenoxo group bridging two metal centres has been synthesized by reacting 4-methyl-2,6-diformylphenol with methyl 2-((2-aminoethyl)amino)cyclopent-1-enedithiocarboxylate. Mono- and binuclear complexes of copper(II), nickel(II), cobalt(II) and zinc(II) have been synthesized and characterized by their UV-vis, IR, H-1 and C-13 NMR and EPR spectra. The electrochemistry of the complexes has been studied and the factors affecting electron-transfer reactions of the binuclear complexes vis-a-vis corresponding mononuclear complexes have been examined.
