This study reveals the crystal structure of a proline-tartaric acid salt. Proline cations and semi-tartrate anions form a layered network via hydrogen bonds, with proline molecules linking tartaric acid chains.

Area of Science:

Crystallography
Supramolecular Chemistry
Chemical Physics

Background:

Proline, an amino acid, and tartaric acid are important organic molecules with diverse applications.
Understanding the solid-state structures of their salts can provide insights into intermolecular interactions.

Purpose of the Study:

To determine the crystal structure of the proline-tartaric acid salt.
To elucidate the hydrogen bonding network and supramolecular architecture in the solid state.

Main Methods:

Single-crystal X-ray diffraction was employed to analyze the crystal structure.
Analysis of hydrogen bonding and intermolecular interactions was performed.

Main Results:

The salt crystallizes with proline as a cation and tartaric acid as a semi-tartrate anion.

Related Experiment Videos

Semi-tartrate anions form hydrogen-bonded chains along the c-axis.

These chains are interconnected by proline cations, forming a layered network parallel to the bc plane.

Proline molecules exhibit weak C-H-O hydrogen bonding interactions.

Conclusions:

The study successfully characterized the supramolecular assembly in the proline-tartaric acid salt.
The findings highlight the role of hydrogen bonding in organizing organic molecules in the crystal lattice.
This structural information is valuable for designing materials with specific properties.
