 Title    The Structure of Zinc Chloride Complexes in Aqueous Solution  
 Abstract    The structure of zinc chloride complexes with different ratios of chloride to zinc, formed in concentrated ZnCl 2 aqueous solutions, were determined from large-angle X-ray scattering using concentrations of the chloride complexes estimated by complementary Raman spectroscopic mea-surements. The highest chloro complex, [ZnCl 4 ] 2 ~, is tetrahedral with a Zn-Cl bond length of 2.294(4) Ä. The trichloro complex, [ZnCl 3 ]~, which coordinates one water molecule, is pyramidal with the Cl-Zn-Cl angle 111°. The Zn-Cl and the Zn-H 2 0 bonds are 2.282(4) and 1.9 A, respec-tively. The two lower complexes, [ZnCl 2 ] and [ZnCl] + , cannot be separated by Raman spectra. o The average Zn-Cl distance in these complexes is 2.24 Ä, and the average Zn-H 2 Ö distance is 1.9 A. In [Zn(H 2 0) 6 ] 2+ the Zn-H 2 0 distance is 2.15 Ä. of zinc (II) chloride complexes; structure of hydrated non-complexed zinc (II) ion.
