Conclusion
The study presents a new polymorph of 2,6-bis(trifluoromethyl)benzoic acid with distinct hydrogen-bonded dimeric orientations.
Supporting Evidence
- The new polymorph contains five independent molecules forming hydrogen-bonded dimers.
- The structural difference from the first polymorph is the orientation of the carboxylic acid functionalities.
Takeaway
Scientists found a new version of a chemical compound that forms in a special way when it crystallizes, which is different from the earlier version.
Methodology
The compound was crystallized from solvent-free oil, and its structure was analyzed using X-ray diffraction.
