The local structures of molten BiCl$$_3$$ and its mixtures in LiCl-KCl eutectic melt were investigated by X-ray absorption fine structure (XAFS) technique. The 1st Bi-Cl correlation in molten pure BiCl$$_3$$ shows covalent nature, since the distance was almost the same as sum of covalent radii of Bi and Cl and the coordination number was almost 3. The similar property was observed also in the mixture of 75% BiCl$$_3$$ with LiCl-KCl eutectic melt. Drastic change was detected in 25% BiCl$$_3$$ mixture melt. The 1st Bi-Cl distance was sum of ionic radii in molten 25% BiCl$$_3$$ melt. The results suggest that BiCl$$_3$$ changes from molecular liquid to ionic by mixing with alkali chlorides.

The structure of 1-ethyl-3-methylimidazolium bifluoride (EMImF$$cdot$$HF) melt has been analyzed at 333 K by a high-energy synchrotron X-ray diffraction method. The total correlation function of the EMImF$$cdot$$HF melt was similar to that of the solid state, indicating that not only the short-range but also the intermediate-range ordering in the solid are partially preserved in the liquid state. The intra-molecular F-F correlation in the anions clearly appears in the total correlation function of the EMImF$$cdot$$HF melt, whereas prominent peaks are not observed in the case of a room temperature molten salt, 1-ethyl-3-methylimidazolium fluorohydrogenate (EMImF$$cdot$$2.3HF).
