Views of the crystal packing of (I). (a) Corrugated sheets that run approximately parallel to the (001) plane. (b) A view along the c axis. A representative π–π contact is shown in this view (lower centre) as a dashed line between benzene-ring centroids, represented by spheres (red in the electronic version of the paper). Hydrogen bonds and other close contacts are also drawn as dashed lines. |
