This study reveals that the title compound, C(18)H(28)Br(2)O(2), exhibits a centrosymmetric structure where alkyl chains are planar and aligned with the benzene ring. These molecular arrangements lead to the formation of one-dimensional supramolecular structures through intermolecular bromine interactions.
Area of Science:
- Crystallography
- Supramolecular Chemistry
- Organic Chemistry
Background:
- Understanding molecular packing and intermolecular interactions is crucial for designing materials with specific properties.
- Centrosymmetric organic compounds with extended alkyl chains and aromatic cores are of interest for their structural and potential electronic characteristics.
Purpose of the Study:
- To elucidate the crystal structure and supramolecular assembly of the title compound, C(18)H(28)Br(2)O(2).
- To investigate the role of intermolecular interactions in dictating the solid-state architecture.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
- Analysis of interatomic distances and angles to identify significant intermolecular interactions.
Main Results:
- The title compound crystallizes in a centrosymmetric manner.
- Alkyl chains adopt a fully extended all-trans conformation and are coplanar with the benzene ring.
- Significant intermolecular Br⋯Br interactions (3.410(3) Å) were observed, leading to a one-dimensional supramolecular architecture.
Conclusions:
- The observed molecular planarity and specific intermolecular Br⋯Br interactions are key factors in the formation of the 1D supramolecular structure.
- This structural insight provides a basis for understanding structure-property relationships in similar organic compounds.
