Abstract :
This paper describes spectroscopic studied of copper (II) complexes with amino acids as ligands. The samples of mixed ligand Copper II with Pyridine -2-Carboxamide and Amino acids were prepared by chemical root method. X-ray absorption spectra of mixed ligand copper complexes at the K-edge of copper have been recorded at the recently developed EXAFS beam line set-up at the Indus-2 synchrotron source at RRCAT, Indore (M.P). The experimental data has been analysed using XAFS data analysis program Athena and the computer software Origin 6.0 professional. The k-absorption (EK) and the energy of the principal absorption maximum (EA) of copper metal and its complexes, edge width, percentage covalency and effective nuclear charge were determined in the present study.
