Figure 8
Three views of the extended structure of (3), along the (a) a, (b) b and (c) c directions. The view along a is parallel to the helical axis and shows the relationship of the helices and the cations; the view along b is a space-filling plot showing the helices running along the a direction and cross-linked by S⋯I interactions; the view along c provides an orthogonal aspect of the helices and cations. |
