Heterometallic cluster-based indium-organic frameworks.

Area of Science:

• Materials Science
• Inorganic Chemistry
• Crystallography

Background:

• Metal-organic frameworks (MOFs) offer tunable structures for various applications.
• Incorporating multiple distinct metal clusters within a single framework presents significant synthetic challenges.

Purpose of the Study:

• To synthesize a novel heterometallic cluster-based indium-organic framework.
• To investigate the structural characteristics and porosity of the new material.
• To explore the sorption properties of the synthesized framework.

Main Methods:

• Ligand-oriented synthesis approach.
• Single-crystal X-ray diffraction for structural determination.
• Gas sorption analysis (e.g., N2 adsorption-desorption isotherms).

Main Results:

• Successfully embedded independent copper-based units (Cu4I4 clusters) into an indium-organic framework, coexisting with In3O(CO2)6 clusters.
• The resulting heterometallic framework displays significant porosity with prominent open channels along the c-axis.
• Initial investigations into the framework's sorption capacity were conducted.

Conclusions:

• This work demonstrates the first successful integration of independent copper clusters within an indium-organic framework system.
• The synthesized material possesses unique structural features, including large porosity and defined channels.
• The findings open avenues for developing advanced materials with tailored sorption properties.
