Figure 6
Space-filling views (van der Waals radii) of the one-dimensional chains that characterize the extended structure of (II)[link]. The Z-shaped π-stacked assemblies give rise to two-dimensional sheets parallel to (010) with a thickness equal to the unit-cell b axis. The sheet mid-point is defined by the (020) plane. The diagram in (a) shows three such sheets stacked along [010] in a projection approximately down [100], and the diagram in (b) represents the view down [010]. Individual one-dimensional hydrogen-bonded chains are highlighted with a single shade to emphasize the propagation of each chain axis along [100].
