EXAFS and XRD studies of copper and cobalt complexes of amino acid

The present paper deals with the synthesis of transition metal schiff base complexes of Para amino benzoic acid (PABA) by chemical root method. The synthesized metal complexes were characterized by XRD analysis, Extended X-ray absorption fine structure (EXAFS) is a technique that has been used for determining the metal ligand bond length using conventional X-ray source and also by EXAFS analysis using IFEFFIT programming. Bond lengths determined from these data analysis methods are compared with the bond lengths obtained from LSS, Levy's and Lytle's methods. All the complexes show the crystalline simple cubic structure. Bond lengths of the complexes are in good agreement obtained by theoretical and experimental methods.
