Zeolite Y of unit-cell composition Na55Si137Al55O384 was NH+4-exchanged and treated with CuCl2 by solid-state ion exchange (SSIE) methods. It was partially dehydrated under vacuum at 100°C to give Cu24-Y. Repeated rehydration with D2O and evacuation

Partial Structures of Fully Dehydrated Ni30Na7Cl12Si137Al55O384 (Solid-State Nickel(II)-Exchanged Zeolite Y) and of Its D2O Sorption Complex by Pulsed-Neutron Diffraction

Ni2+-exchanged zeolite Y was prepared by solid-state ion-exchange methods (Ni30Na7Cl12Si137Al55O384·nH2O per unit cell) and was fully dehydrated (Ni30−Y). Rehydration with D2O and evacuation at 24 °C yielded a second sample (Ni30−Y·D2O). Pulse
