Electron and X-ray scattering as well as Raman spectra of as aqueous solution of ZnBr2 with a Br−/Zn++ ratio of 3: 1 have been studied. The existence of hexaaquo, di-, tri- and tetra-bromo complexes in solution has been established by all three methods. Octahedral hexaaquo and tetrahedral Zn(H2O)4−nBrn complexes with n = 2, 3, 4 are consistent with electron and X-ray structure functions. The inner sphere type complexes have interatomic distances of 2.2 Å for Zn++−H2O, 2.4 Å for Zn++−Br−, 3.93 Å for Br−-Br− and 2.91 Å for W-W interactions with average numbers of contacts 2.4, 2.22, 1.33 and 1.1 respectively.
