The study determined the 3D structure of a brominated organic compound, C(13)H(9)BrO(2). Its benzene and furan rings are twisted at a 44.35-degree angle, with no close intermolecular contacts in its crystal form.
Area of Science:
- Crystallography
- Organic Chemistry
- Materials Science
Background:
- Understanding the three-dimensional structure of organic molecules is crucial for predicting their properties and reactivity.
- Brominated organic compounds are important intermediates in various chemical syntheses.
Purpose of the Study:
- To elucidate the crystal structure and molecular geometry of the title compound, C(13)H(9)BrO(2).
- To analyze the intermolecular interactions and packing in the solid state.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular structure.
- Crystal structure analysis was performed to investigate molecular conformation and packing.
Main Results:
- The dihedral angle between the benzene and furan rings was determined to be 44.35(14)°.
- Analysis of the crystal packing revealed no unusually short intermolecular contacts, indicating typical van der Waals interactions dominate.

Structure and Nomenclature of Ethers
Ethers are organic compounds with an ether functional group which is characterized by an oxygen atom connected to two — identical or different — alkyl, aryl, or vinyl groups. The C–O–C linkage in dimethyl ether — the simplest ether — has an approximately tetrahedral bond angle of 110.3 degrees. The oxygen atom is sp3- hybridized, with the C–O distance being about 140 pm.
