“…Therefore the quinone is simultaneously involved in both X‐bonding and lp–π interactions, which are important in the solid‐state architecture of this molecule. The second structure that we selected is a trans ‐stilbene‐based compound (QOSCAD,34 see Figure 3) that has iodo and cyano substituents strategically positioned to form an infinite 1D molecular chain dominated by CN ⋅⋅⋅ I contacts (3.042 Å and 172.5°). These infinite 1D chains form a 2D layer by means (among others) of lp–π contacts between the iodine atom and the electron‐deficient tetrafluorobenzonitrile ring (3.732 Å).…”

“…A recent study by Mariaca et al 14,36 has shown the influence of fluorination on the crystal packing of donor-acceptor substituted stilbenes. A series of substituted halogeno-cyanostilbenes (Fig.…”

“…[14] and references therein). As in the case of substituted stilbenes, already partial substitution can alter the crystal packing dramatically [14b,c] . However, under the isolated conditions of the gas phase, free of packing effects, there are fewer examples of this type of exchange and its effects.…”
