Conclusion
The study presents the crystal structure of tetrabutylammonium 4-hydroxybenzoate dihydrate, highlighting the role of water molecules in the structure's stability.
Supporting Evidence
- The carboxyl group of the p-hydroxybenzoate anion is slightly twisted with respect to the phenyl ring.
- The structure features wide hydrogen-bonded ribbons formed by interactions between the anion and water molecules.
- Tetrabutylammonium cations create unclosed diamond-like channels that contain the hydrogen-bonded ribbons.
Takeaway
This study shows how a specific chemical compound forms a stable structure with the help of water molecules.
Methodology
The compound was synthesized by dissolving p-hydroxybenzoic acid in a water-ethanol mixture and adding tetrabutylammonium hydroxide, leading to the formation of colorless block crystals.
