Abstract
Several new complexes of the Schiff base obtained by the condensation of gl ycyl-DL-alanine with 2,4-dihydroxybenzaldehyde were synthesized. The comple xes were characterized by elemental analyses, conductivity measurements, in frared and electronic spectra and H-1 NMR. The ligand is coordinated to the central metal as tetradentate ONNO ligand. The bonding sites are the carbo xylate oxygen, imino nitrogen, amide nitrogen and phenolic oxygen.
