X-ray diffraction and X-ray K absorption near edge studies of copper (II) complexes with amino acids

Synthesis of copper (II) complexes [CuL₁L₂X].nH₂O, where n=1, 2,3 (X=Cl,Br,NO₃) (L₁is 2,2'-bipyridine and L₂ is L-tyrosine) by the chemical root method. The XRD data for the samples have been recorded. EXAFS spectra have also been recorded at the K-edge of Cu using the dispersive beam line BL-8 at 2.5 Gev Indus-2 Synchrotron radiation source at RRCAT, Indore, India. XRD and EXAFS data have been analysed using the computer software. X-ray diffraction studies of all complexes indicate their crystalline nature. Lattice parameter, bond length, particle size have been determined from XRD data. (paper)
