Figure 9
(a) The 4V2 `shoelace' unit-distance graph where R〈T–T〉 = 91.301–116.635 Å and is thus incompatible where k = 0.001 and K = −50. In an attempt to decrease R〈T–T〉, k is increased to 0.0025 and the unit-distance graph in (b) is produced where R〈T–T〉 = 74.139–91.431 Å and R〈T⋯T〉min = 57.597–59.950 Å. Thus, one may conclude this chain graph is incompatible as any further increase in k, in an attempt to reduce R〈T–T〉, will result in a decrease in R〈T⋯T〉min to values below γ = 58 Å. This is shown in (c) where k is increased to 0.02 and the resultant unit-distance graph does not converge. |
