New polymorph of 2,6-dimethylphenol

Key Points

• Distinct intermolecular interactions characterized the new orthorhombic polymorph of 2,6-dimethylphenol, enhancing hydrogen bonding effects.
• The monoclinic form had previously been documented, but here, its structure was redetermined alongside the discovery of the new form.
• Crystallographic analysis revealed significant differences in the packing of hydrogen-bonded chains between the two polymorphs.
• These findings advance our understanding of polymorphism in small organic molecules and their crystallographic behaviors.
