Area of Science:

• Crystallography
• Organic Chemistry
• Supramolecular Chemistry

Background:

• Understanding the three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties.
• Intermolecular interactions, such as hydrogen bonds and pi-stacking, significantly influence crystal packing and material characteristics.

Purpose of the Study:

• To elucidate the crystal structure of the title compound, C(19)H(13)NO(2).
• To analyze the spatial relationship between the pyridyl and phenanthrene ring systems.
• To identify and describe the intermolecular forces governing crystal assembly.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular structure.
• Crystallographic analysis was performed to measure bond lengths, angles, and dihedral angles.
• Analysis of intermolecular interactions, including hydrogen bonds and C-H⋯π interactions, was conducted.

Main Results:

• The pyridyl ring is nearly perpendicular to the phenanthrene ring system, with a dihedral angle of 87.04°.
• The crystal structure is stabilized by weak intermolecular C-H⋯O hydrogen bonds.
• C-H⋯π interactions were also identified as a contributing factor to crystal packing.

Conclusions:

• The determined crystal structure provides a detailed understanding of the molecular geometry of C(19)H(13)NO(2).
• The identified intermolecular interactions highlight the importance of non-covalent forces in the self-assembly of this organic compound.
• This structural information can serve as a basis for further studies on the compound's physical and chemical properties.
