Abstract X-ray K-absorption spectroscopic studies have been carried out on the copper (II) mixed-ligand complex [Cu(SA)2(Py)2] where ligands SA= Salicylic acid and Py= Pyridine. XAFS spectra have been recorded at the K-edge of copper using the dispersive beam line at 2.5GeV Indus-2 synchrotron radiation source RRCAT(Raja Ramanna Center for Advance Technology ), Indore, India. XAFS data analysis program Athena and the computer software Origin 6.0 professional have been used to processed the obtained data. Various X-ray absorption parameters e.g., chemical shift, edge-width and shift of the principal absorption maximum have been obtained in the present study. The chemical shift data have been utilized to estimate effective nuclear charge on the absorbing atom. The XAFS data obtained has also been used to determine the bond length by using four different methods, i.e., Levy’s, Lytle, Lytle, Sayers and Stern’s (LSS) and Fourier transformation methods. The results of the study have been reported in this paper.
