Conclusion
The study presents the crystal structure of a compound formed by tetramethylammonium and terephthalate ions, revealing a unique sandwich-like arrangement.
Supporting Evidence
- The crystal structure features a dihedral angle of 23.5° between the carboxylate group and its parent ring.
- Two independent water molecules act as both donors and acceptors in the hydrogen-bonded host layers.
- The tetramethylammonium cations are arranged in two rows between the host layers.
Takeaway
Scientists created a special crystal using certain chemicals, and it looks like a sandwich with layers.
Methodology
The compound was synthesized by dissolving biphenyl-4,4'-dicarboxylic acid in a water-ethanol mixture and adding tetramethylammonium hydroxide.
