2,2,2-Tribromo-N-(4-chloro-phen-yl)acetamide

Area of Science:

• Crystallography
• Solid-state chemistry
• Molecular structure

Background:

• Understanding the intermolecular interactions and crystal packing of halogenated organic compounds is crucial for predicting their physical and chemical properties.
• Hydrogen bonding plays a significant role in determining the supramolecular architecture of crystalline solids.

Purpose of the Study:

• To elucidate the crystal structure of the title compound, C(8)H(5)Br(3)ClNO.
• To investigate the types and directions of hydrogen bonding present in the crystal.
• To describe the resulting supramolecular arrangement.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of hydrogen bonding interactions, including distances and angles.

Main Results:

• The crystal structure of C(8)H(5)Br(3)ClNO was successfully determined.
• Intra-molecular N-H⋯Br and inter-molecular N-H⋯O hydrogen bonds were identified.
• Molecules are arranged in column-like chains along the c-axis via N-H⋯O hydrogen bonding.

Conclusions:

• The crystal packing is governed by a combination of intra- and inter-molecular hydrogen bonds.
• The observed chain-like structure is a direct consequence of the specific hydrogen bonding network.
