5-(4-Chloro-phen-yl)-2-fluoro-pyridine.

Area of Science:

• Crystallography
• Organic Chemistry
• Materials Science

Background:

• Understanding the solid-state structure of halogenated aromatic compounds is crucial for predicting their physical and chemical properties.
• The specific arrangement of functional groups in organic molecules influences intermolecular interactions and crystal packing.

Purpose of the Study:

• To determine the precise three-dimensional structure of the title compound, C(11)H(7)ClFN.
• To investigate the intermolecular interactions and crystal packing of this halogenated heterocyclic compound.

Main Methods:

• Single-crystal X-ray diffraction was employed to analyze the crystal structure.
• The molecular geometry and crystal packing were examined based on the diffraction data.

Main Results:

• The chloro-benzene and 2-fluoro-pyridine rings exhibit a dihedral angle of 38.83(5) degrees.
• Analysis of the crystal structure confirmed the absence of significant hydrogen bonding interactions between molecules.

Conclusions:

• The determined dihedral angle provides insight into the preferred conformation of the molecule in the solid state.
• The lack of hydrogen bonding suggests that other intermolecular forces, such as van der Waals interactions, dominate the crystal packing.
