Synthesis and characterization of 2,2-(terephthaloyl)‎ bis (azanediyl)‎ bis (3-mercapto propanoic acid)‎ and its complexes with some metal Ions

Abstract EN

The ligand 2, 2َ-(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] .
