Preparation, thermogravimetric and spectroscopic studies of transition metal complexes of schiff base condensation ligands

Schiff-base compound of beta- alanine with benzaldehyde [1] was prepared and allowed to react with urea under retluxing condition and the resulting product[II] was reacted with two moles of oxalic acid to obtain compound [III]. The behavior of the prepared compound [111] as a ligand [L] towards metal acetate to form metal complexes were studied. The metal-L complexes were prepared in the mole ratio 2L: 1 M and the prepared complexes were characterized on the basis of the following: elemental analyses UV, IR, [1]H NMR spectra, conductometric titration, magnetic susceptibility and theimogravemrtric analysis [TGA]
