Abstract
The main problem attacked in this investigation is the nature of the bonding in transition metal-ETTA [(Ethanediylidenetetrathio)tetracetic Acid] complexes, whether it occurs through sulfur, oxygen or both. The author feels the bonding occurs through both sulfur and oxygen and in a tetrahedral configuration a- bout the central metal ion. | In this investigation the synthesis of both 1st and 2:1 metal to ligand ratio complexes of transition metals Cobalt (II), Nickel (II), Copper (II), Iron (II), Manganese (II), and Zinc (II) with ETTA were attempted. The complexes were all isolated from an aqueous solution of the ligand and the metal carbonate. The complexes were sent out for C, H, and S analysis to confirm the nature of the complexes.
