Figure 4
Distribution of mean [4]Si–O distances for structures with a mean coordination number for O2− of [4]. The range of mean Si–O values taken from the trend line on the graph of Brown & Gibbs (1969BB6), and the sum of the [4]Si4+ and [4]O2− radii from Shannon (1976BB45) are shown; from Gagné & Hawthorne (2017bBB14).
