Smolin et al.

have introduced CdS clusters in pores of zeolite-Z. It is
shown that these clusters are built up around the S atoms that are situated at the
centers of the large cavities of zeolites and coordinated tetrahedrally by Cd atoms.
These atoms are bound through sulfur atoms with Cd cations situated near the walls
of the cavity in the environment of the aluminosilicate framework oxygen.
