Conclusion
The crystal structure of the organic salt shows a specific arrangement of cations and anions with defined angles between them.
Supporting Evidence
- The cations pack head-to-tail within a sheet and are aligned in opposite directions in neighboring sheets.
- The benzene ring of the anion makes an angle of 76.99° with the plane of the cationic chromophore.
- The unit cell contains two cations, two anions, and two water molecules.
Takeaway
Scientists studied a special salt that forms crystals, and they found out how the parts of the salt fit together in a specific way.
Methodology
The crystal was grown by slow evaporation from a saturated solution of the compound in methanol and water.
