“…As a result, the directed assembly of compositionally and structurally complex architectures requires a thorough understanding of the way in which complementary and competing forces eventually lead to a stable solid-state architecture [6,7]. Against this background, our goal was to establish reliable and robust avenues for the design and synthesis of crystalline metal-containing materials by encoding each building-block with structural-preferences that lead to "programmable" and predictable assembly [8][9][10].…”

“…In the field of crystal engineering driven by halogen bond, it has been observed that the replacement of an iodine atom with a bromine atom in a molecule weakly affects its overall crystal packing leading, in most of the cases, to isostructural systems . Based on this consideration, we did not expect remarkable differences in the overall crystal packing between KLVFF(Br) and its iodinated derivative.…”

“…Additionally, it is worthy of mention that the presence of halogens affects the supramolecular patterns in the Fmoc-AA family. In particular, in XATKEL (Pizzi et al, 2017), C-IÁ Á Á interactions between an I atom and fluorenyl [IÁ Á Á(centroid of phenyl ring) distance is 3.829 Å and C-IÁ Á Á(centroid of phenyl ring) angle is 165.27 ] give rise to the formation of supramolecular rings. In XATJAG (Pizzi et al, 2017), those rings are created by C-BrÁ Á Á interactions.…”
