TLDR
In this article, the authors compared the solid state structures of particular benzoates and corresponding acids 1-4 both in the non-spacered (1, 2) and spacered (3, 4) forms.Abstract:
Considering the specific supramolecular synthon design of carboxylic acid and alcoholic hydroxyl groups in the field of crystal engineering, we compared the solid state structures of particular benzoates and corresponding acids 1–4 both in the non-spacered (1, 2) and spacered (3, 4) forms. Based on the single crystal X-ray study, there is only a slight influence of the phenylacetylene spacer with regard to the layer lattice arrangement of the benzoates while referring to the benzoic acid analogues the addition of the spacer gives rise to a modification of the lattice from a layer to a tape structure. Dependent on the crystallization conditions, two crystalline polymorphs of compound 3 (3a, 3b) were obtained and discussed regarding their structural differences.read more

On the origin of surfaces-dependent growth of benzoic acid crystal inferred through the droplet evaporation method
Piotr Cysewski,Piotr Cysewski,Maciej Przybyłek,Tomasz Miernik,Mirosław Kobierski,Dorota Ziółkowska +5 more
TL;DR: In this paper, the growth behavior of benzoic acid crystals on different surfaces was examined and the presence of very strong influence introduced by polar surfaces such as glass, gelatin, and polyvinyl alcohol (PVA) on the growth of BAs was examined.

Fine-tuning of packing architecture: symmetrically bridge-disubstituted tetramethoxycalix[4]arenes
TL;DR: In this article, three acetonitrile solvates of tetramethoxycalix are equally substituted on opposite methylene bridges with respect to their conformation and packing behaviour, all of the host molecules adopt a 1,2-alternate conformation, their packing architecture seems to be affected by the spatial demand of the bridge substituents only.

Patterns in Hydrogen Bonding: Functionality and Graph Set Analysis in Crystals
TL;DR: In this article, a review of the most promising systematic approaches to resolving this enigma was initially developed by the late M. C. Etter, who applied graph theory to recognize, and then utilize, patterns of hydrogen bonding for the understanding and design of molecular crystals.

Supramolecular Synthons in Crystal Engineering—A New Organic Synthesis
TL;DR: In this article, the authors show that crystal engineering is a new organic synthesis, and that rather than being only nominally relevant to organic chemistry, this subject is well within the mainstream, being surprisingly similar to traditional organic synthesis in concept.
