Conclusion
The study reports the crystallization of benzilic acid in a monoclinic polymorph, providing detailed structural information.
Supporting Evidence
- The asymmetric unit contains two complete molecules.
- Classical hydrogen bonds and C—H⋯O contacts connect the molecules to infinite chains along the c-axis direction.
- The structure was refined as a two-component twin with a volume ratio of 73.6:26.4.
Takeaway
The researchers found a new form of benzilic acid that has a different structure than previously known forms.
Methodology
The compound was synthesized and crystallized from THF, and its structure was analyzed using diffraction studies.
