Synthesis and Characterization of Co(II), Ni(II), Cu(II), and Zn(II) Complexes with a New vic-Dioxime (E,E)-N′-Hydroxy-2-(Hydroxyimino)-N-(4-{[(2-Phenyl-1,3-Dioxolan-4yl)Methyl]Amino}Butyl)Ethanimidamide1

Abstract

A new vic-dioxime ligand containing 1,3-dioxolane ring and 1,4-diaminobutane, (E,E)-N′-hydroxy-2-(hydroxyimino)-N-(4-{[(2-phenyl-1,3-dioxolan-4-yl)methyl]amino}butyl)ethanimidamide (H₂L) and the metal mononuclear complexes with a 1 : 2 and 1 : 1 metal–ligand ratio have been prepared with chloride salts Co(II), Ni(II), Cu(II), and Zn(ll) in EtOH. The structures of the ligand and its complexes have been established by microanalyses, IR, UV-VIS, ¹H and ¹³C NMR spectra, elemental analyses, and conductivity and magnetic susceptibility measurements. Also their thermal behavior has been studied by the TGA analysis.
