Molecular dynamics calculations are carried out for two Coulombic glasses, LiCl and LiCl‐KCl‐CsCl. Stillinger‐Weber’s inherent structures (the configurations of potential minima) which ions in glassy state undergo during 100 ps were explored for two systems. The ions in the LiCl‐KCl‐CsCl glass diffuse collectively via the successive potential basins whose minima are distributed along zigzag ways. On the contrary, in pure LiCl glass several ions transit to the next potential basins while the remaining ions continue to stay at almost the same potential basins.
