The local structure of molten CdCl and CdCl-KCl mixture was investigated by high-temperature XAFS technique. The nearest Cd-Cl distance decreases by melting. Similarly, the coordination number decreases from 6 to 4. It suggests that there is (CdCl) tetrahedral complex ion in the melt. It is concluded that the local structure is kept also in the mixture melt, since the same XAFS result as the pure melt was obtained.
