N-(4-Chloro-phen-yl)quinolin-2-amine.

Area of Science:

• Crystallography
• Organic Chemistry
• Molecular Structure

Background:

• The molecule C(15)H(11)ClN(2) exhibits specific structural characteristics.
• Understanding molecular conformation is crucial for predicting chemical and physical properties.

Purpose of the Study:

• To elucidate the crystal structure and intermolecular interactions of C(15)H(11)ClN(2).
• To investigate the influence of molecular conformation on crystal packing.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular structure.
• Analysis of intermolecular contacts, including C-H⋯N and C-H⋯π interactions, was performed.

Main Results:

• A notable dihedral angle of 18.85(9)° was observed between the quinoline and benzene rings, indicating a twisted molecular conformation.
• A short C-H⋯N contact was identified, with the amine hydrogen and quinoline nitrogen atoms oriented oppositely.
• Supramolecular layers were formed in the ab plane through C-H⋯π interactions in the crystal lattice.

Conclusions:

• The observed twisted conformation of C(15)H(11)ClN(2) is a key feature influencing its crystal packing.
• Intermolecular C-H⋯N and C-H⋯π interactions play a significant role in mediating the formation of layered supramolecular structures.
