The reaction of two equivalents of cystamine [2-mercaptoethyl ammonium chloride] with one equivalent of cisdichloroethene in a methanolic solution of potassium hydroxide gave the diamine compound which reacted in suit with 2,6-diformyl -4- methyl phenol to give cyclic ligand with N2OS2 donor atoms is formed [H1L]. Also neutral complexes of this ligand with different metal ions were prepared. Ligand and its complexes were characterized by microanalysis spectroscopic methods [FT-IR, U.V- Vis, NMR, Mass], a long with molar conductivity and magnetic moment measurements from the above data the proposed molecule structure was suggested.
