Area of Science:

• Crystallography
• Organic Chemistry
• Supramolecular Chemistry

Background:

• Understanding molecular conformation and crystal packing is crucial in materials science and drug design.
• Hydrogen bonding plays a significant role in determining the solid-state structure of organic molecules.

Purpose of the Study:

• To elucidate the crystal structure and intermolecular interactions of the title molecule C(14)H(10)BrClN(3)O(2).
• To investigate the role of hydrogen bonding in stabilizing the molecular conformation and directing crystal packing.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the three-dimensional structure of the molecule.
• Analysis of bond lengths, bond angles, and intermolecular contacts was performed.

Main Results:

• The title molecule C(14)H(10)BrClN(3)O(2) adopts an approximately planar conformation with a dihedral angle of 5.79(12)° between aromatic ring planes.
• Intramolecular hydrogen bonds (O-H⋯N and N-H⋯O) were identified, contributing to conformational stability.
• An intermolecular O-H⋯O hydrogen bond links molecules into chains propagating along the [001] direction in the crystal.

Conclusions:

• The crystal structure reveals specific hydrogen bonding patterns that dictate the solid-state arrangement of C(14)H(10)BrClN(3)O(2).
• The findings contribute to the understanding of structure-property relationships in halogenated organic compounds.
