Abstract
Di[4-(11-chloro-3,6,9-trioxaundecyloxy)phenylamino]glyoxime (LH2) has been prepared from 1-amino-4-(11-chloro-3,6,9-trioxaundecyloxy)benzene, anti-dichloroglyoxime, and sodium carbonate in ethanol. Nickel(II), copper(II) and cobalt(II) complexes of the ligand were synthesized. The Cu(II), Ni(II) and Co(II) complexes of the vic-dioxime ligand LH2 have a metal/ligand ratio of 1:2 and the ligand coordinates only through the N, N atoms, as do most vicinal dioximes. The structures of the ligand and its complexes were investigated by elementel analyses, magnetic susceptibility measurements, 1H NMR, IR and U.V.-Visible spectroscopy.
