Area of Science:

• Organic Chemistry
• Crystallography
• Materials Science

Background:

• Synthesis of novel organic compounds is crucial for developing new materials.
• Understanding molecular structure and intermolecular interactions informs material properties.
• Fluorinated organic molecules offer unique electronic and physical characteristics.

Purpose of the Study:

• To synthesize a novel fluorinated organic compound.
• To characterize the synthesized compound's structure using X-ray crystallography.
• To investigate the intermolecular interactions within the crystal lattice.

Main Methods:

• The title compound, C(30)H(32)FNO(2), was synthesized via a multi-component reaction involving dimedone, 4-fluoro-benzaldehyde, and p-toluidine in an aqueous medium.
• Single crystals of the synthesized compound were obtained for X-ray diffraction analysis.
• The crystal structure was analyzed to determine molecular geometry and intermolecular interactions.

Main Results:

• The synthesized compound, C(30)H(32)FNO(2), was successfully prepared.
• X-ray crystallography revealed that the dihydro-pyridine and cyclo-hexenone rings adopt non-planar, flattened boat conformations.
• A dihedral angle of 15.33(3)° was measured between the planar aromatic rings.
• Intermolecular C-H⋯O hydrogen bonds were identified, leading to the formation of centrosymmetric dimers in the crystal structure.

Conclusions:

• The successful synthesis and structural elucidation of the novel fluorinated organic compound are reported.
• The non-planar ring conformations and the presence of intermolecular hydrogen bonds dictate the compound's solid-state packing.
• This study provides insights into the structural features of fluorinated heterocyclic compounds and their self-assembly behavior.
