Two new sodium N-phthalyl amino acid ligands (L1) and (L2) were prepared by the reaction of phthalic anhydride with glycine or alanine amino acids the sodium salt of the above ligand were prepared by the reaction with sodium hydroxide. The mono and dinuclear complexes of Cr +3, Fe +3, Co +2, Ni +2, Cu +2 and Zn +2 were prepared by the reaction of the above ligands with the metal chloride in (1:1)or (1:2) metal to ligands ratio. The ligands and their complexes have been characterized by their analytical, spectral data, conductivity and magnetic measurements. Electronic spectra and magnetic measurements indicates that the mononuclear complexes contain tetrahedral environment, while the dinuclear complexes have octahedral geometry.
