Conclusion
The crystal structure of 5,17-dibromo-26,28-dihydroxy-25,27-dipropoxy-2,8,14,20-tetrathiacalix[4]arene reveals a pinched cone conformation stabilized by intramolecular hydrogen bonds.
Supporting Evidence
- The thiacalix[4]arene unit adopts a pinched cone conformation.
- Two intramolecular O—H⋯O hydrogen bonds stabilize the cone conformation.
- Two different chains of molecules are formed by intermolecular π–π stacking interactions.
Takeaway
Scientists studied a special molecule called dibromothiacalix[4]arene and found that its shape is like a pinched cone, which helps it hold together better.
Methodology
The compound was prepared using a published procedure, and single crystals were obtained for X-ray diffraction analysis.
