X-ray K-absorption spectroscopic studies have been carried out on three copper (II) mixed-ligand complexes .The complexes are [Cu(L6)2(H2O)2(Cl)](0.2)H2O, [Cu(L6)2(H2O)2(SO4)](0.2)H2O and [Cu(L6)2(H2O)2(Br)](0.2)H2O where ligand L6= (p-methoxy anilino) –P– chloro phenyl acetonitrile. XAFS spectra have been recorded at the K-edge of Cu using the dispersive beam line at 2.5GeV Indus-2 synchrotron radiation source RRCAT(Raja Ramanna Center for Advance Technology ), Indore, India. The data obtained has been processed using XAFS data analysis program Athena and the computer software Origin 6.0 professional. 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. Further the observed chemical shifts have been correlated with percentage covalency in these complexes. The studies establish significant correlation between various parameters for these complexes. 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.
