Figure 4
The crystal packing of the 2-isomer. (a) The view direction is approximately perpendicular to the ab plane. Atom radii are arbitrary and only H atoms participating in hydrogen bonding are included. Hydrogen bonds and Cl⋯Cl interactions (see text) are shown as dashed lines. Molecules shown with thin bonds are farther away from the viewer. (b) Perpendicular view on to the layer at y ≃ (classical hydrogen bonds are not involved in these layers; see text). |
