Abstract

 
The reaction of an equivalent of 2- mercaptoethyl ammonium chloride with an equivalent of 2,6-diformyl -4- methyl phenol produced monoamine which was reacted with half equivalent of 1,2-diamine ethane to produce ethylene-bis-6-(2-mercapto-ethyl-imine)-methyl -4- methyl phenol [H4L]. The ligand was reacted with metal ions[Cr(III), Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), and Hg(II)] at reflux ethanol, under nitrogen at atmosphere. The ligand and derivative 2,6-diformyl-4-methylphenol and metal ion complexes were characterized by elemental microanalysis, IR, UV, (1H, 13C, 1H-1H, 1H-13C)NMR and mass spectroscopies and suggested structures and octahedral for the complexes [Cr, Mn, Co, and Ni] while complexes of [Fe, Zn, Cd, and Hg] suggested tetrahedral geometry and a distorted square planar geometry around copper complex.
