Conclusion
The study presents the crystal structure of a hydrated salt formed from guanidine and 4,5-dichlorophthalic acid, revealing a duplex-sheet structure stabilized by hydrogen bonds.
Supporting Evidence
- The structure features two guanidinium cations and a water molecule forming hydrogen bonds with the dianion.
- The carboxyl groups of the dianion are rotated out of the plane of the benzene ring.
- Duplex-sheet structures are formed, extending down the (011) planes in the unit cell.
Takeaway
The researchers looked at how a specific salt made from guanidine and a type of acid is arranged in a crystal, showing how the pieces fit together like a puzzle.
Methodology
The compound was synthesized by heating 4,5-dichlorophthalic acid and guanidine carbonate in ethanol-water, followed by crystallization.
