Cu K-edge extended X-ray absorption fine structure(EXAFS) spectra have been obtained for four copper (II) mixed ligand complexes using BL-8 Dispersive Extended X-ray Absorption Fine Structure (EXAFS) beamline at the 2.5-GeV INDUS-2 Synchrotron Source, RRCAT(Raja Ramanna Center for Advance Technology),Indore, India. The complexes are [Cu(ben)(p-Tol)(Cl)2], [Cu(ben)(p-Tol)(CH3COO)2], [Cu(ben)(p-Tol)(NO3)2] and [Cu(ben)(p-Tol)(Br)2]. The ligand (p-methyl anilino) phenyl acetonitrile was prepared which included the reaction of benzaldehyde with P-toluidine. The data obtained has been processed using EXAFS data analysis program Athena and the computer software Origin 6.0 professional. EXAFS maxima and minima positions have been obtained from the normalized spectra. The normalized EXAFS spectra have been Fourier transformed. The position of the first peak in the Fourier transform gives the value of first shell bond length .This distance is the phase-uncorrected bond length and has also been determined by Lytle, Sayers and Stern s (LSS) graphical method. It is found that the results obtained from LSS and the Fourier transformation methods are in good agreement with each other, i.e. both the LSS method and Fourier transformation method give nearly the same value of the phase-uncorrected bond lengths. In this paper, the first shell bond length has also been estimated by Lytle’s and Levy’s methods from the EXAFS data.
