Figure 6
Fragments of the γ-HNIW (a) and ∊-HNIW (b) crystal structures projected onto the (Q1, Q3) plane of thermal expansion, with intermolecular distances shorter (>7% reduction) than the sum of the van der Waals radii shown by dashed lines. The directions of the Q1, Q3 eigenvectors are shown along with the relative magnitudes of their eigenvalues coded red (positive) and blue (negative). |
