Abstract

Neutron powder diffraction was used to study Linde Y-zeolite from which Al was removed by treatment with NH₃/steam or with gaseous SiCl₄. The first treatment gave a framework composition Si_139.7Al_52.3O₃₈₄ with a 24.358(1) A at 293 K (space group Fd3m); the second Si_173.1Al_18.9O₃₈₄ with a 24.188(1) A at 293 K and 24 K and 24.171(1) A at 573 K. Rietveld refinement and difference Fourier syntheses establish the presence of a tetrahedrally coordinated Al species in the centre of the sodalite unit.-J.E.C.
