The crystal structure of a novel brominated fluorinated organic compound reveals a near-planar conformation between its benzene rings. Intramolecular hydrogen bonds create specific ring structures within the molecule.
Area of Science:
- Crystallography
- Organic Chemistry
- Supramolecular Chemistry
Background:
- Understanding molecular conformation and intermolecular interactions is crucial in crystal engineering.
- The study of halogenated organic compounds provides insights into structure-property relationships.
Purpose of the Study:
- To elucidate the crystal structure and intermolecular interactions of the title compound, C(13)H(9)BrFNO.
- To investigate the conformational preferences and hydrogen bonding patterns in this novel organic molecule.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the molecular structure.
- Analysis of the crystal structure included bond lengths, bond angles, and dihedral angles.
Main Results:
- The dihedral angle between the substituted benzene rings in C(13)H(9)BrFNO was found to be 9.00(11)°, indicating a nearly planar arrangement.
- Strong intramolecular O-H⋯N hydrogen bonds were identified, forming characteristic S(6) ring motifs.
Conclusions:
- The title compound exhibits a conformationally constrained structure due to significant intramolecular hydrogen bonding.
- The identified S(6) ring motifs are a key feature influencing the packing and properties of the crystal structure.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
