Octaspherosilicate structures have found use as scaffolds for dendrimer synthesis, as models for aluminosilicate structures, and as supports for organometallic catalysts. Space-filling models of such cages suggest there is a void at the center of the cube, but that it is questionable whether it could be filled by an atomic species. Päch and Stosser have shown that g-irradiation of octaalkyl octasilsesquioxane or octatrialkyl siloxyoctasilsesquioxane leads to hydrogenencapsulated
T8 or Q8 cages. ESR spectroscopy confirmed that the hydrogen originated from the organic substituents of the cage.
