1-(2-Naphth-yl)-3-phenyl-prop-2-en-1-one

Area of Science:

• Crystallography
• Organic Chemistry
• Supramolecular Chemistry

Background:

• Understanding the solid-state structure of organic molecules is crucial for predicting their properties.
• The presence of conjugated systems and specific functional groups can influence molecular conformation and packing.
• Intermolecular interactions, such as C-H⋯π bonding, play a significant role in crystal engineering.

Purpose of the Study:

• To elucidate the crystal structure and molecular conformation of the title compound, C(19)H(14)O.
• To investigate the intermolecular interactions governing the crystal packing.
• To characterize the supramolecular architecture formed in the solid state.

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 details.
• Intermolecular interactions were identified and analyzed using geometric criteria.

Main Results:

• The title compound, C(19)H(14)O, crystallizes with two independent molecules in the asymmetric unit.
• Both molecules adopt an s-cis conformation around the ketone group and exhibit non-planar structures.
• Significant dihedral angles between the benzene and naphthalene ring systems were measured (51.9(1)° and 48.0(1)°).
• Intermolecular C-H⋯π interactions were observed, stabilizing a two-dimensional supramolecular array parallel to the ab plane.

Conclusions:

• The study provides a detailed structural characterization of C(19)H(14)O in the solid state.
• The observed non-planar conformation and specific dihedral angles are key features of this molecule.
• C-H⋯π interactions are critical in directing the self-assembly into a 2D supramolecular network.
