Summary
This study details the crystal structure of a new melaminium salt, 2,4,6-triamino-1,3,5-triazin-1-ium chloride hemihydrate. The compound forms a 3D network via hydrogen bonds between melaminium, chloride, and water molecules.
Area of Science:
- Crystallography
- Materials Science
- Supramolecular Chemistry
Background:
- Melaminium salts are of interest due to their potential applications.
- Understanding the crystal structure is crucial for predicting material properties.
Purpose of the Study:
- To characterize the crystal structure of a novel melaminium salt, 2,4,6-triamino-1,3,5-triazin-1-ium chloride hemihydrate.
- To elucidate the hydrogen bonding network within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the crystal structure.
- Analysis of intermolecular interactions, including hydrogen bonds, was performed.
Main Results:
- The crystal structure consists of single-protonated melaminium cations, chloride anions, and water molecules.
- Melaminium cations are located on a twofold axis, with chloride anions and water molecules on the m plane.
- N-H...N hydrogen bonds link melaminium residues into chains parallel to the (001) plane.
- These chains form a three-dimensional network through interactions with chloride anions and water molecules.
Conclusions:
- The novel melaminium salt exhibits a complex three-dimensional hydrogen-bonded network.
- The structural arrangement suggests potential for tailored material properties based on hydrogen bonding.
- Further studies can explore the physical and chemical properties arising from this unique crystal structure.
