The crystal structure of a C(20)H(15)N(2)O(+)·Cl(-) compound reveals a significant dihedral angle. Hydrogen bonds and aromatic π-π stacking influence its molecular arrangement in the solid state.
Area of Science:
- Crystal Engineering
- Supramolecular Chemistry
- Organic Chemistry
Background:
- Understanding intermolecular forces is crucial for designing novel materials.
- Crystal structure analysis provides insights into molecular packing and interactions.
Purpose of the Study:
- To elucidate the crystal structure and intermolecular interactions of the title compound.
- To investigate the role of hydrogen bonding and π-π stacking in the solid-state arrangement.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, bond angles, and non-covalent interactions was performed.
Main Results:
- The crystal structure of C(20)H(15)N(2)O(+)·Cl(-) was determined.
- A dihedral angle of 63.10(7)° was observed between the fused-ring system and the benzene ring.
- N-H⋯Cl hydrogen bonds and aromatic π-π stacking (shortest centroid-centroid distance = 3.6421(12) Å) were identified as key interactions.
Conclusions:
- The crystal packing is governed by a combination of hydrogen bonding and π-π stacking interactions.
- These interactions dictate the overall supramolecular architecture of the compound in the solid state.
