Abstract: The main aim of this paper was to study the effect of a new tripodal chelating agent on La1−xSr xCo1−yFeyO3−δ perovskite prepared by the complexation method. For this purpose, a phenolic derivative of glycine (L) was synthesized applying the Mannich reaction and characterized by NMR and IR spectroscopies as well as by elemental analysis. To evaluate the complexation capability of L, its formation constants with the perovskite cations were measured. Comparison of these results with those reported for the complexaion with glycine, introduced L as a good candidate for the complexation with Fe(III) and La(III) cations. Furthermore, the powder XRD observations confirmed an improvement in the perovskite formation in the presence of L.

Keywords: amino acid – perovskite – coordination – UV-VIS – X-ray diffraction
