Figure 28
The e/n ratio of chain graphs with e/n = 1.0–2.0 as a function of rigidity (mi/m). Each green box represents a unique chain topology observed in minerals. The area shaded in pale green represents the range in e/n ratio for chains in minerals and the area shaded in pink represents the range in e/n ratio for chains that are not observed in minerals. Note the sharp increase in rigidity at e/n = 1.5. |
