| Abstract: | Mono-and mixed-ligand complexes with the composition [Ni(Cyt)2(H2O)2]Cl2, [Ni(Thr–)2(H2O)2] and [Ni(Thr–)(Cyt)(H2O)2]Cl are synthesized and studied. Using IR spectroscopy it is determined that in the complex compounds, cytosine is bidentate (C=O group oxygen and heterocycle N3), threonine interacts with the Ni(II) ion due to amino and carboxyl groups. The models of the atomic structure of the studied compounds are proposed based on the EXAFS and XANES spectroscopy results. |
