Abstract
A SiO2 material with the lowest framework density (15.4 SiO2 nm–3) and the largest void volume fraction (nearly 50%) ever reported for crystalline silica polymorphs has been synthesised, and its structure solved by direct methods and fully refined using low-resolution powder X-ray diffraction data.Keywords
