Abstract

Two novel Schiff base ligands containing oxyethylene glycol chains, N-(4-pentaoxyethyleneglycolphenyl)salicylaldimine, HL1, and N-(4-nonaoxy ethyleneglycolphenyl)salicylaldimine, HL2, were synthesized by reacting salicylaldehyde with 4-aminophenylpentaoxyethylene glycol or S-amino phenylnonaoxyethylene glycol, respectively. Their nickel(II), copper(II) and cobalt(II) complexes were synthesised. The novel Schiff base ligands and their complexes were characterized by elemental analyses, H-1 NMR, infrared and UV-Visible spectra. The analytical data show that the metal to ligand ratio in the complexes is 1:2.
