Evolution of the intermolecular distances for the different phases of DME (red), DEE (green) and DPE (blue) with pressure. The two shortest distances for the two types of interactions are presented: full shapes represent H⋯H and empty shapes represent H⋯O distances. The black horizontal lines show the sum of the van der Waals radii (Bondi, 1964BB900) of hydrogen and oxygen (2.72 Å) and of hydrogen and hydrogen (2.4 Å); the vertical dashed lines mark the limits of the pressure stability ranges of individual crystal phases. The estimated standard deviations are smaller than the plotted symbols.
