摘要：

Aluminate sodalites containing the telluride and tellurite ions have been synthesised for the first time. The structures of Sr-8[AlO2](12)(TeO3)(2) and its reduced product Sr-8[AlO2]Te-12(2) have been determined using Rietveld refinement of powder neutron diffraction data. In Sr-8[AlO2]Te-12(2) the anion occupies a position at the sodalite cage centre, whilst in Sr-8[AlO2](12)(TeO3)(2) the larger tellurite ion is displaced to allow reasonable coordination to the strontium ions. The reduction of the occluded TeO32- to Te2- has also been investigated using IR spectroscopy, Al-27 and Te-125 MAS NMR spectroscopies and Te L(III)-edge EXAFS.
