Abstract

Mixed salts AgBr_0.6Cl_0.4 and their pure components were investigated by XAFS. The concentration of the mixture was chosen to produce the homogeneous phase. Detailed analysis of the Ag and Br K edge data revealed an angular deviation of bonds in the mixture from collinearity. The corresponding RMS buckling angles (11 ± 2°) were determined using the strong angular dependence of the forward scattering amplitude in double- and triple-scattering focusing paths. The XAFS results were used to perform molecular-dynamics simulations which allowed to visualize the actual structure of the mixture.
