Abstract :
The present paper deals with the synthesis of transition metal complexes of Copper by chemical rout method. The complexes have been synthesized by condensation of o-phenylenediamine, diethyl malonate and diazonium ion in the ethanolic medium, through refluxing with Cu (II) metal salt. Synthesized metal complexes were characterized by X-ray diffraction (XRD) and studied by X-ray absorption structure (XAS) spectroscopy. The XAS technique includes XANES (X-ray Absorption near Edge structure) and EXAFS (Extended X-ray Absorption Fine Structure) spectroscopy. XANES spectra have been recorded at the K-edge of Cu using the dispersive EXAFS (DEXAFS) beam line at 2.5GeV Indus-2 synchrotron radiation source RRCAT, Indore, India. The XANES data have been analysed using the computer software Athena. These have been used to determine the chemical shift, edge width, and nature of complexes. XRD analysis shows that sample is crystalline in nature. The XRD pattern is made by using Bruker D-8 advance instrument.
