abstract = {The synthetic leucite silicate framework mineral analogues
Cs$_{2}$XSi$_{5}$O$_{12}$ (X = Cu, Cd, Zn) were prepared by
high-temperature solid-state synthesis. The results of
Rietveld refinement, using 18 keV synchrotron X-ray powder
diffraction data collected at low temperatures (8K X = Cu,
Zn; 10K X = Cd) show that the title compounds crystallize in
the space group Pbca and are isostructural with the ambient
temperature structures of these analogues. The structures
consist of tetrahedrally coordinated SiO$_{4}$ and XO$_{4}$
sharing corners to form a partially substituted silicate
framework. Extraframework Cs cations sit in channels in the
framework. All atoms occupy the 8c general position for this
space group. In these refined structures, silicon and X
atoms are ordered onto separate tetrahedrally coordinated
sites (T-sites).},
