| Popis: | An understanding of the driving forces resulting in crystallization vs organogel formation is essential to the development of modern soft materials. In the molecular structure of the title compound, methyl 10-[4-(4-hydroxyphenyl)phenoxy]decanoate (MBO10Me), C23H30O4, the aromatic rings of the biphenyl group are canted by 6.6 (2)° and the long-chain ester group has an extended conformation. In the crystal, molecules are linked by O—H...O hydrogen bonds, forming chains along [10\overline{3}]. The chains are linked by C—H...O hydrogen bonds, forming layers parallel to the ac plane. The layers are linked by C—H...π interactions, forming a three-dimensional supramolecular structure. The extended structure exhibits a lamellar sheet arrangement of molecules stacking along the b-axis direction. Each molecule has six nearest neighbors and the seven-molecule bundles stack to form a columnar superstructure. Interaction energies within the bundles are dominated by dispersion forces, whereas intercolumnar interactions have a greater electrostatic component. |
