Conclusion
The study presents the crystal structure of a coumarin derivative, revealing its molecular geometry and interactions.
Supporting Evidence
- The dihedral angle between the phenyl ring and the 2H-chromene ring system is 59.8°.
- The crystal packing is stabilized by weak π–π stacking interactions.
- There are intermolecular C—H⋯O hydrogen-bonding interactions that stabilize the structure.
Takeaway
The researchers looked at a special chemical compound and found out how its atoms are arranged and how they interact with each other.
Methodology
The crystal structure was determined using X-ray diffraction techniques.
