3-Methyl-2-vinyl-pyridinium phosphate

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 dictating crystal packing and properties.

Purpose of the Study:

• To elucidate the crystal structure of the title salt (C8H10N(+)·H2PO4 (-)).
• To investigate the hydrogen bonding interactions and supramolecular assembly in the crystal lattice.

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 C-H⋯O contacts was performed.

Main Results:

• The cation (C8H10N+) was found to be essentially planar.
• Phosphate anions formed inversion dimers and extended chains via O-H⋯O hydrogen bonds.
• Cations and anions were linked through N-H⋯O hydrogen bonds and C-H⋯O contacts.

Conclusions:

• The crystal structure reveals a well-defined network of hydrogen bonds dictating the arrangement of cations and anions.
• The observed supramolecular architecture provides insights into the solid-state behavior of this organic salt.
