Conclusions

Water molecules in partially dehydrated zeolite directly interact with Na+ cations. The final three or four water molecules per unit cell removed upon the dehydration of zeolite are apparently bound to Na+ cations of the eight-membered windows, while the previous ∼10 molecules are bound to Na+ cations of six-membered windows.
