Hypothesis
The title compound adopts a 1,2-alternate conformation and is suitable for constructing metallo-supramolecular architectures.
Conclusion
The crystal structure of the compound reveals significant intramolecular and intermolecular interactions that may stabilize the crystal packing.
Supporting Evidence
- The calix[4]arene unit displays a 1,2-alternate conformation with crystallographic inversion symmetry.
- The four phenoxy rings are twisted about the mean plane with specific dihedral angles.
- Intramolecular C—H⋯π interactions and intermolecular C—H⋯Br hydrogen bonds contribute to the crystal stability.
Takeaway
Scientists made a special molecule called calix[4]arene that can change shape, and they found out how it fits together in crystals.
Methodology
The compound was synthesized through refluxing calix[4]arene with caesium carbonate and 1-bromo-3-(methylbromo)benzene, followed by crystallization.
