Abstract

Naphthalene based schiff-base compounds were synthesized by a condensation reaction of one equivalent of 1,5-diamino naphthalene and two equivalents of 2-hydroxy-3-methoxy benzaldehyde as previously described[1]. The metals selected for the preparation of complexes were La(III) and Er(III) as nitrate salts Hence, in total two metal complexes were synthesized , have been characterized by molar conductivity measurements, elemental analysis, infrared and Uv-vis. Spectral data were used to investigate the geometrical structure of the prepared complexes. La(111) complex was further identified using 1H-NMR and 13C-NMR spectral. The results suggest that the Ligand acted as a neutral tridentate, coordinated through the oxygen atom (-OH) and azomethine nitrogen –CH=N-, and five water molecules out of the coordination sphere. The nitrate ions are bi- dentately coordinated to the metal ion. Which form very stable complexes with the Lanthanide metals (Ln3+). A Coordination number of nine may be assigned to the metal ion in the synthesized complexes the geometrical shap is tricapped trigonal prismatic . Biological activity studies on the representative have been done succefully.
