Background:

• Understanding the self-assembly of organic salts is crucial for designing new materials.
• Crystal structure analysis provides fundamental insights into molecular interactions and network formation.

Purpose of the Study:

• To elucidate the crystal structure and intermolecular interactions of the title compound, C(8)H(9)N(+)·H(2)PO(4) (-).
• To investigate the role of hydrogen bonding and π-π stacking in the formation of extended networks.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of hydrogen bonding (O-H⋯O, N-H⋯O) and π-π stacking interactions was performed.

Main Results:

• The title compound crystallizes with both cation and anion exhibiting crystallographically imposed mirror symmetry.
• Chains parallel to the b axis are formed through O-H⋯O and π-π stacking interactions (centroid-centroid distance = 3.4574(6) Å).
• A two-dimensional network is assembled via N-H⋯O hydrogen bonds connecting adjacent chains.

Conclusions:

• The crystal structure demonstrates a well-defined arrangement driven by specific intermolecular forces.
• The observed network formation highlights the potential for this compound in supramolecular chemistry applications.
