Tetra-ethyl-ammonium l-malate 1.36-hydrate

Area of Science:

• Crystallography
• Supramolecular Chemistry
• Chemical Physics

Background:

• The study investigates the solid-state structure of a specific chemical compound.
• Understanding crystal packing and intermolecular forces is crucial for predicting material properties.

Purpose of the Study:

• To elucidate the crystal structure of C(8)H(20)N(+)·C(4)H(5)O(5) (-)·1.36H(2)O.
• To characterize the hydrogen bonding network and its role in crystal stabilization.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the crystal structure.
• Analysis of intra- and intermolecular hydrogen bonds was performed.

Main Results:

• The asymmetric unit contains two independent ion pairs and partially occupied water molecules.
• Intramolecular hydrogen bonds form five-membered rings.
• Intermolecular interactions lead to the formation of 1D chains along the a-axis and molecular sheets parallel to the (001) plane.

Conclusions:

• The crystal structure is stabilized by a combination of intra- and intermolecular O-H···O and C-H···O hydrogen bonds.
• The observed hydrogen bonding network dictates the supramolecular architecture.
