Abstract :
Schiff base condensation of benzil bis o-phenylenediamine with acetophenone, benzophenon, acetone, benzaldehyde and p-chlorobenzaldehyde and its Copper complexes were synthesised. Preparation of the free ligands was accomplished by refluxing benzil with o-phenylenediamine in 1:10 mole ratio in methanol. XANES 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 Centre for Advance Technology ), Indore, India. The K-absorption (EK) and the energy of the principal absorption maximum (EA) of copper metal and its complexes, edge width and effective nuclear charge were determined in the current study. These studies build prominent interaction between various parameters for the Cu-complexes. XANES data have been analysed using the computer software Athena and Origin. The values of the chemical shifts specify that copper is in oxidation state +2 in all of the complexes.
