Compounds of the formula Na-8[Si(6 + y)BeyAl(6 - 2y)O(24)]X-2, with X = Cl and Br, and y = 1, 2 and 3 have been synthesised and structurally characterised by combined powder X-ray and neutron diffraction pro. le analysis. These materials adopt the sodalite framework ( SOD) with the tetrahedral species, BeO4, AlO4 and SiO4, disordered across the framework positions. Na-8[Si8Be2Al2O24]Cl-2, (y = 2), is a synthetic analogue of the naturally occurring semi-precious gemstone tugtupite, while Na-8[Si9Be3O24]X-2, X = Cl and Br represents a new tetrahedral framework stoichiometry with a Si : Be ratio of 3 : 1. Additional characterisation using Si-29 MASNMR, IR spectroscopy and high-temperature, neutron diffraction show that the observed structure - property trends found when modelling sodalite materials can be extended to these new framework compositions.
