(2-Amino-ethan-1-aminium-κN ²)tri-chlorido-zinc(II)

Area of Science:

• Inorganic Chemistry
• Crystal Engineering
• Coordination Chemistry

Background:

• Zwitterionic complexes offer unique structural and electronic properties.
• Hydrogen bonding plays a crucial role in the self-assembly of supramolecular structures.
• Zinc(II) complexes are widely studied for their diverse coordination geometries and applications.

Purpose of the Study:

• To synthesize and characterize a novel mononuclear zwitterionic zinc(II) complex.
• To investigate the coordination environment and crystal packing of the complex.
• To explore the role of hydrogen bonding in forming supramolecular frameworks.

Main Methods:

• Single-crystal X-ray diffraction to determine the molecular and crystal structure.
• Spectroscopic techniques for characterization (e.g., IR, NMR - though not explicitly mentioned, implied for characterization).
• Analysis of intermolecular interactions, particularly hydrogen bonding.

Main Results:

• A mononuclear zwitterionic zinc(II) complex, [ZnCl3(C2H9N2)], was successfully synthesized.
• The complex exhibits a distorted tetrahedral coordination geometry around the zinc(II) center.
• The crystal structure reveals extensive intermolecular hydrogen bonding between amine/ammonium groups and chloride atoms, forming a supramolecular framework.

Conclusions:

• The synthesized complex demonstrates the formation of zwitterionic zinc(II) coordination compounds.
• Hydrogen bonding is a key driving force for the self-assembly into extended supramolecular structures.
• The study contributes to understanding the crystal engineering of metal-organic materials.
