Figure 5
Graphical representations of the population of known compounds with a tri­methoxy­phenyl­ethenyl fragment (a) versus the angle their outer rings make with the double-bond vector and (b) versus the angle between the ring and the extra-annular single-bond vector. Shaded bars indicate data for 3,4,5-trimethoxy-substituted compounds and open bars indicate data for 2,4,6-trimethoxy-substituted compounds.
