Figure 3
(a) Face-to-face stacking gives rise to a chain of antiparallel-pillared molecules of derivative (II). The angle between the least-square planes calculated through C atoms of rings A and B and the non-H atoms bridging them is shown. (b) Hydrogen-bonding pattern responsible for cross-linking the chains of stacked molecules, as shown in the previous panel. Hydrogen⋯oxygen distances are displayed (values in Å). Symmetry operators: (i) $[{1\over 2}- x, 1 - y, -{1\over 2} + z]$ ; (ii) x, y, - 1 + z; (iii) $[{1\over 2} - x, 1 - y, {1\over 2} + z]$ . (c) Top view of seven chains of stacked units of derivative (II) distributed over the (100) plane. (d) Representation of the dipole-moment directions (black and grey arrows refer to molecules packed on the top and the bottom of the projection plane).
