Synthesis and Characterization of 2,2◌َ-(Terephthaloyl) bis (azanediyl) bis (3-mercapto propanoic acid) and its Complexes with some Metal Ions

Abstract

The ligand 2,2◌َ-(Terephthaloyl) bis (azanediyl) bis (3-mercapto propanoic acid)
(TAMPA) was synthesized from the reaction of terephthaloyl chloride with cysteine, it
has been characterized and its structure was elucidated depending upon elemental
analysis (CHNS) and spectral data (IR , UV-Vis) . Series of metal complexes of the
deprotenated ligand with ions such as Mn(II) , Co(II) , Ni(II) , Cu(II) and Zn(II) have
been synthesized and characterized by (FT-IR) , (UV-Vis) spectroscopy , flame atomic
absorption technique, magnetic susceptibility and conductivity measurements. The
following general formula were suggested [M2(TAMPA)(H2O)4] .
