4-Sulfamoylanilinium chloride.

Area of Science:

• Crystallography
• Chemical Physics
• Materials Science

Background:

• Understanding the supramolecular assembly of organic salts is crucial for designing new materials.
• Hydrogen bonding plays a key role in directing crystal packing and network formation.
• The specific interactions within 4-sulfonamido-anilinium chloride warrant detailed structural investigation.

Purpose of the Study:

• To elucidate the crystal structure of the title compound, C(6)H(9)N(2)O(2)S(+)·Cl(-).
• To identify and characterize the intermolecular interactions governing the solid-state architecture.
• To understand the role of hydrogen bonding in forming a three-dimensional network.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of hydrogen bonding networks (N-H⋯Cl and N-H⋯O) was performed.
• Structural visualization and analysis of the resulting three-dimensional framework.

Main Results:

• The crystal structure consists of discrete 4-sulfonamido-anilinium cations and chloride anions.
• Chloride anions are positioned between layers formed by the organic cations.
• A robust three-dimensional network is established through extensive N-H⋯Cl and N-H⋯O hydrogen bonds.

Conclusions:

• The crystal packing is dominated by electrostatic interactions and directional hydrogen bonding.
• The observed network structure highlights the self-assembly capabilities of sulfonamide-containing organic salts.
• This structural insight provides a foundation for further studies on related compounds and their potential applications.
