Abstract :
This paper deals with the X-ray absorption near edge structural studies of transition metal Schiff base complexes of Cu(II), derived from benzil-2,4-dinitrophenylhydrazone with different anilines, that have been prepared by chemical root method. These synthesized complexes have been characterized by Cu K-Edge XANES measurements using the BL-8 Dispersive EXAFS beamline at 2.5 GeV Indus-2 synchrotron radiation source at RRCAT (Raja Ramanna Centre for Advance Technology), Indore, India. The measured XANES data have been analyzed to compute the energies of the K absorption edge, chemical shifts, shifts of the principal absorption maximum and edge-widths. The values of the chemical shift suggest that copper is in oxidation state +2 in all of the complexes. By calculating the chemical shift effective nuclear charge on copper atom has been estimated. All these calculation has been done with computer software ATHENA.
