Question: The internuclear distances in gas-phase ionic molecules are considerably smaller than those in the corresponding crystals. For example, the internuclear distance in NaCl(g) is 2.3606

The internuclear distances in gas-phase ionic molecules are considerably smaller than those in the corresponding crystals. For example, the internuclear distance in NaCl(g) is 2.3606 , whereas in NaCl(s) the shortest Na-Cl distance is 2.814 . Explain why this should be so when the binding energy is larger in the crystal
