【 摘 要 】

Synthesis of metal complexes [Cu (Carbamide)] (X = Br, Cl, NO3, SO4,CH3COO) by the chemical root method. The XRD data have been recorded at DAE, IUC Indore.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 Center for Advance Technology), Indore, India. XRD and XANES data have been analysed using the computer software Origin 8.0 professional and Athena. X-ray diffraction studies of all the complexes are indicative of their crystalline nature. The crystalline size of the samples is estimated using the Scherer's formula. The values of the chemical shifts suggest that copper is in oxidation state +2 in all of the complexes.
