Morpholinium 4-amino-5-meth-oxy-2-methyl-benzensulfonate

Area of Science:

• Crystallography
• Supramolecular Chemistry
• Materials Science

Background:

• Understanding the self-assembly of organic salts is crucial for designing new materials.
• Hydrogen bonding plays a key role in directing crystal packing and forming extended structures.

Purpose of the Study:

• To elucidate the crystal structure of the title compound, C(4)H(10)NO(+)·C(8)H(10)NO(4)S(-).
• To investigate the role of hydrogen bonding in the formation of supramolecular architectures.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of intermolecular interactions, specifically hydrogen bonds, was performed.

Main Results:

• The crystal structure consists of protonated 2-aminoethanol cations (C(4)H(10)NO(+)) and sulfanilate anions (C(8)H(10)NO(4)S(-)).
• Components are linked by N-H⋯O hydrogen bonds, forming centrosymmetric 2:2 aggregates.
• These aggregates are further connected by anion-mediated N-H⋯O hydrogen bonds, resulting in a double-tape structure along the a axis.

Conclusions:

• The study successfully determined the crystal structure and identified the hydrogen bonding network.
• The observed double-tape structure highlights the ability of these organic salts to form extended supramolecular assemblies.
• This structural information can guide the design of novel crystalline materials with specific properties.
