Conclusion
The crystal structure of the compound shows that the components are held together by hydrogen bonds, forming a 2:1 aggregate.
Supporting Evidence
- The anion lies on an inversion center.
- The aggregates are connected by multiple types of hydrogen bonds.
- The nearest centroid separation between naphthalene rings suggests no π–π stacking.
Takeaway
Scientists studied a special compound made of two parts that stick together. They found out how these parts are arranged and held together.
Methodology
The compound was synthesized by mixing naphthalene-1,5-disulfonic acid and ethanolamine in ethanol and cooling the solution to form crystals.
