Sodalites of the composition Cd[BeGeO]X X = S, Se, Te have been synthesised by hydrothermal reaction of CdO, BeO, GeO and X at 750°C and 2kbar. The materials crystallise with the cubic sodalite unit cell with an ordered Be/Ge framework in the space group P43n. Their structures have been refined from powder x-ray diffraction data in order to delineate the dimensions of the CdX units in the sodalite cage and the intercage separation of these units. Infra-red, UV-VIS spectra of these materials are also reported. UV-VIS data demonstrate that the CdX units do not interact electronically.
