Statistical analysis of the Bach—Bach distances in the channels. (a) and (b) t-Plots of the closest Bach—Bach distances and their statistical distribution at (a) 16.5 and (b) 19.6 GPa. Each solid line corresponds to a distance varying between 2.9 and about 7 Å. The domain intervals indicate one (dark grey) and two (light grey) interatomic contacts associated with the formation of dumb-bells and triplets, respectively, in the 2.9–3.8 Å range. (c) The pressure dependence of the dumb-bell and triplet content.
