This study details the crystal structure of a bromo-butyl carbazole derivative. The molecule exhibits a zigzag conformation and weak intermolecular van der Waals interactions in its solid state.
Area of Science:
- Organic Chemistry
- Crystallography
- Solid-State Chemistry
Background:
- Carbazole derivatives are important in materials science and medicinal chemistry.
- Understanding the solid-state structure is crucial for predicting material properties and designing new compounds.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(16)H(16)BrN.
- To analyze the molecular conformation and intermolecular interactions in the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, bond angles, and dihedral angles provided conformational insights.
Main Results:
- The bromo-butyl group adopts a zigzag conformation, oriented to one side of the carbazole ring plane.
- A small dihedral angle of 0.55° was observed between the two benzene rings of the carbazole moiety.
- Intermolecular interactions in the crystal are primarily van der Waals forces.
Conclusions:
- The determined crystal structure provides a fundamental understanding of the solid-state behavior of this bromo-butyl carbazole derivative.
- The conformational and packing details are essential for structure-property relationship studies in related carbazole compounds.
