Aqua(benzene-1,3-dicarboxylato)zinc(II)

Area of Science:

• Materials Science
• Crystallography
• Coordination Chemistry

Background:

• Metal-organic frameworks (MOFs) are advanced materials with tunable structures.
• Zinc-based MOFs are of interest for their diverse applications.
• Understanding the formation and properties of novel MOFs is crucial for materials development.

Purpose of the Study:

• To synthesize and characterize a new metal-organic coordination network based on zinc and isophthalate.
• To elucidate the structural features and bonding interactions within the novel framework.
• To investigate the origin of the observed polar structural pattern.

Main Methods:

• Single-crystal X-ray diffraction to determine the crystal structure.
• Infrared spectroscopy to confirm functional groups and coordination.
• Analysis of bond distances, angles, and intermolecular interactions.

Main Results:

• The compound poly[[aquazinc(II)]-mu-benzene-1,3-dicarboxylato-O1:O1':O2], [Zn(C8H4O4)(H2O)]n, was successfully synthesized.
• A two-dimensional coordination network with tetrahedral zinc centers was formed.
• Chiral framework structures were observed, linked by hydrogen bonding interactions.

Conclusions:

• The synthesized material forms a chiral, polar metal-organic framework.
• Distorted tetrahedral geometry of zinc centers and water molecule alignment contribute to the polar structure.
• The study provides insights into the design principles for chiral MOFs.
