Synthesis and Characterization of Multimetallic Fe(II) and Mn(II) Using N4O3 Potentially Heptadentate Ligand

A Mustapha, SM Gani

Abstract


Potentially heptadentate (N4O3) tripodal Schiff-base ligand, tris(5-Bromo-2-hydroxybenzylaminoethyl)amine has been prepared and characterized using various spectroscopic methods. It is derived from the condensation reactions of tris(2-aminoethyl)amine (tren), with 3 equivalents of 5-bromo-2-hydroxybenzaldehyde. Iron(II) and Manganese(II) complexes of the resulting ligand were obtained from its reactions with Fe(II) and Mn(II) salts in absolute methanol for the metal to ligand ratio 2:3. These complexes were characterized by Solubility, Conductivity, IR and UV-VIS spectrometry, elemental analysis and mass spectrometry.

Keywords: Iron, Manganese, Schiff- base, Tren5BrSal, tris-(2-aminoethyl)amine
