Summary
This study investigates the co-crystal structure of glycine and tartaric acid. The research reveals a three-dimensional hydrogen-bonded network formed by zwitterionic glycine and tartaric acid molecules.
Area of Science:
- Crystallography
- Supramolecular Chemistry
- Materials Science
Background:
- Co-crystals are crystalline solids composed of two or more different molecular components.
- Understanding the hydrogen bonding interactions in co-crystals is crucial for designing new materials with specific properties.
Purpose of the Study:
- To elucidate the crystal structure of the glycine-tartaric acid co-crystal.
- To analyze the hydrogen bonding network within the co-crystal.
Main Methods:
- Single-crystal X-ray diffraction was used to determine the molecular and crystal structure.
- Analysis of intermolecular interactions, including hydrogen bonds, was performed.
Main Results:
- The glycine molecule exists in a zwitterionic form within the co-crystal.
- Tartaric acid molecules form inversion dimers through O-H⋯O hydrogen bonds.
- A 3D network is formed by O-H⋯O and N-H⋯O hydrogen bonds between glycine and tartaric acid.
Conclusions:
- The crystal structure reveals a complex hydrogen bonding network involving both glycine and tartaric acid.
- The zwitterionic nature of glycine plays a key role in the network formation.
- The study provides insights into the supramolecular assembly of organic co-crystals.
