Schiff base condensation of benzil bis o-phenylenediamine with acetophenone, benzaldehyde and P-cloro benzaldehyde and its Cobalt complexes were synthesized. Preparation of the free ligands was accomplished by refluxing benzyl with o-phenylenediamine in 1:10 mole ratio in methanol. The XRD and EXAFS characterization of benzil bis ophenylenediamine based macro cyclic complexes of Cobalt was undertaken. From the result of investigations of XRD particle size and lattice parameter have been

EXAFS spectra have been recorded at the K-edge of Co using the dispersive EXAFS beam line at 2.5 GeV Indus-2 synchrotron radiation source RRCAT, Indore ,India .From the fine structure data the average metal-ligand bond distances have been estimated. Bond lengths for Co-complexes have been determined with the help of Levy's, LSS, Lytle's, Fourier transform methods.
