Local Atomic Environment of Zn2+ Ions in a Low-Concentration ZnCl2 Aqueous Solution: XANES Study

The diverse local environment of zinc ions in a ZnCl 2 solution, depending on the symmetry, ligand type, and solution concentration, has been analyzed using the data in the literature. Experimental zinc K -edge XANES spectra in a ZnCl 2 aqueous solution with a critically low concentration (10 –3 М) have been theoretically analyzed. It is shown that Zn(H 2 O) complexes with Zn 2+ ions in the octahedral coordination environment of water molecules are dominant in this solution.
