Area of Science:

• Crystallography
• Organic Chemistry
• Supramolecular Chemistry

Background:

• Understanding the three-dimensional structure of organic molecules is crucial for predicting their properties and interactions.
• Pyridine and naphthalene moieties are common in pharmaceuticals and materials science, making their combined structures of interest.

Purpose of the Study:

• To elucidate the crystal structure and molecular geometry of a novel compound containing pyridine and naphthalene rings.
• To investigate the intermolecular interactions governing the crystal packing of the title compound.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the precise arrangement of atoms in the crystal lattice.
• Analysis of bond lengths, bond angles, and dihedral angles provided insights into the molecular conformation.
• Intermolecular interactions, including hydrogen bonds and C-H···π interactions, were identified and analyzed.

Main Results:

• The pyridine and naphthalene ring systems were found to be nearly coplanar, with a small dihedral angle of 3.3°.
• The pyridine ring and the benzene ring of the naphthalene system exhibited a near-perpendicular orientation (dihedral angle of 89.9°).
• Crystal packing was significantly influenced by intermolecular O-H⋯N hydrogen bonds and C-H⋯π interactions.

Conclusions:

• The study provides a detailed structural characterization of the C(22)H(19)NO compound.
• The observed molecular geometry and crystal packing highlight the importance of non-covalent interactions in stabilizing the solid-state structure.
• These findings contribute to the understanding of structure-property relationships in related organic systems.
