Fast divalent conduction in MB12H12·12H2O (M = Zn, Mg) complex hydrides: effects of rapid crystal water exchange and application for solid-state electrolytes

Water molecules are exchanged in the crystal structure, which imparts a high divalent conductivity to hydrated complex hydrides. MB 12 H 12 ·12H 2 O (M = Zn or Mg) exhibits exceptional conductivities higher than those of less-hydrated complex hydrides.
