Open full text 0 citations

Abstract

A new macrocyclic Schiff base complexes were prepared in the presence of lanthanide metal ion[La(III), Ce(III) and Gd(III)] by the reaction of 2,6 – diamino pyridine, benzoyl aceton and metal ion as template effect in the molar ratio of 2: 2: 1 respectively. The lanthanide metal complexes were characterized and investigated by using; 1HNMR, FTIR, UV/Visible spectroscopy, Elemental analysis (C.H.N.), Magnetic susceptibility and Molar conductivity measurements. The lanthanide metal ions coordinated to six nitrogen atoms of the ligand and three chloride ions to complete geometry of nine coordination complexes.
