Structural properties of zinc halide melts

E.A. Pavlatou, G.N. Papatheodorou

Vibrational Raman spectroscopy has been used to identify and determine the structure of species formed in the binary mixtures ZnCl2-ACl (A=Cs, Li) and ZnCl2-ZnBr2. The data indicate that the network-like structure of the zinc halide melts breaks up with the addition of alkali metal halide and with increasing temperature. The tetrahedral structure around the Zn is preserved but one, two, three or four "terminal" halogen atoms having Aas nearest neighbors are formed. Different bridging bonding states are proposed to exist in the pure ZnCl2 glass and liquid.
