Analysis of chemical shift, shift of principal absorption maxima, edge width, percentage of covalency of Cu(II) complexes

Abstract

The present paper deals with the synthesis of transition metal Schiff base complexes of copper by chemical root method. The nature of the electronic structure and bonding in transition metal compounds is matter of intrinsic interest. High-energy spectroscopic are well suited to provide information on these points. Among them, X-ray absorption spectroscopy (XAS) has been revealed to be a potential tool for determining the electronic and geometrical structure of complex compounds. In particular, K edge and XANES spectra of transition metal complexes have been the topic of several studies. The position and shape of X-ray absorption discontinuities have been used to deduce structural and chemical bonding information on transition metal complexes. The K-absorption spectra were recorded on the synchrotron radiation, i.e., on beamline BL-8 at RRCAT, Indore. Complexes of Cu(II) complexes with thiosemicarbezide as legand have been taken in to consideration and analysis of chemical shift,shift of principal absorption maxima,edge width,percentage of covalency were done.
