Synthesis and characterization of some Lanthanide (III) Ions complexes with Anthranilic-acid and Amino acid phenylalanine

This paper presents the synthesis and identification of some complexes of the (Anthranilic acid )(ligand) symbolized as (A) and some trivalent ions Ln111[ La(III), Ce(I) , Pr(III) , Nd(III) .Gd(III) , Ho (III) and the same ions with the (Phenylalanine ) (ligand) symbolized as Phe). Productsi have been found to be solid crystalline, complexes which have been studied and characterized by the :Thermal stability, solubility, molar conductivity, elemental analysis (C.H.N), magnetic measurements. determination the percentage of the metal in the complexes by (A. A. S) and sepectrosopis methods (Uv-Vis ,IR(. From the above investigations, the general formula has been suggested [M(A-1)3] and M(Phe.1)3] were M111- La(III), Ce(III) , Pr(III) , Nd(III),Gd(III), Ho(III) A-11= C7H6NO2, Phe-11=C9H10NO2.
