A synthesis of transition metal complexes of Cr (ll),Mn (ll) and Cu (ll) from 6,6'-((1E,1'E)-((1,3-phenylenebis(methylene))bis(azanylylidene))bis(methanylylidene))bis(2,4-dibromophenol) have been synthesized and characterized by 1H NMR, IR spectral studies. FTIR spectra confirms that the ligand co-ordinates metal ion to form complex via oxygen and nitrogen atom of the phenolic group and azomethine group respectively. The spectroscopic studies suggested the octahedral structure of Chromium complex, Mn Complex,and Copper Complex have Squre planar Structure . The spectroscopic data of complexes is in agreement with their structure in which N2O2 group act as tetra-dentate ligand and two chlorides as a mono-dentate ligands.
