Abstract :

Presented here is a synthetic strategy for a novel tetradentate Schiff base (H2L) with the formula C18H24O2N2 through a condensation reaction of 1,4-Bis(aminomethyl)benzene and acetylacetone with an approximate yield of 74%. Furthermore, the synthesis and characterization of two Schiff base complexes of Copper [Cu2(L)2] and Cobalt [Co2(L)2(H2O)4]is presented. Characterization of these complexes was performed using UV-VIS spectroscopy; IR spectroscopy; 13C & 1H NMR; and elemental analysis. The results of this analysis revealed that two ligand chains are attached to each metal ion in these complexes. The coordination geometries of the ligands around copper were shown to be squere planar around Cu and octahedral around Co
