9-(Pent-4-en-yl)anthracene
This study reveals the molecular structure of a C(19)H(18) compound, showing an almost planar anthracene core stabilized by C-H⋯π interactions and a non-planar pentene group.
Area of Science:
- Organic Chemistry
- Crystallography
Background:
- Understanding molecular geometry is crucial for predicting chemical properties.
- Anthracene derivatives are important in materials science and organic electronics.
Purpose of the Study:
- To elucidate the three-dimensional structure of the title compound, C(19)H(18).
- To investigate the intramolecular interactions and conformational preferences within the molecule.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the molecular structure.
- Analysis of bond lengths, bond angles, and torsion angles provided structural insights.
Main Results:
- The anthracene core exhibits near planarity (maximum deviation of -0.039 Å).
- Stabilizing C-H⋯π interactions were identified within the crystal structure.
- The pentene moiety is significantly non-planar, with a maximum torsion angle of 91.2° relative to the anthracene system.
Conclusions:
- The C(19)H(18) compound possesses a unique twisted conformation due to the non-planar pentene group.
- The interplay of planarity in the anthracene core and the twisted pentene moiety influences the molecule's overall architecture and potential intermolecular interactions.
