Abstract
Rielveld analysis of synchrotron powder X-ray diffraction data obtained from the product of the reaction of cadmium vapour with dehydrated zinc-exchanged zeolite A (LTA structure type) indicates the formation of cationic zinc-cadmium alloy clusters. The clusters are located in approximately 40% of the sodalite cages; the remaining 60% of the cages contain divalent zinc ions coordinated both to the oxygen atoms of the zeolite framework and to residual extra framework oxygen.
