Hetero-interpenetrating porous coordination polymers

Area of Science:

• Materials Science
• Chemistry
• Crystallography

Background:

• Interpenetrating porous coordination polymers (IPCPs) are intricate materials formed by mechanically interlocked networks.
• Classification of IPCPs relies on framework topology and chemical composition, distinguishing homo-IPCPs from hetero-IPCPs.
• Hetero-IPCPs are less common and their formation is often serendipitous.

Purpose of the Study:

• To highlight the characteristics and classification of heterogeneous interpenetrating porous coordination polymers (hetero-IPCPs).
• To emphasize the importance of framework topology and chemical composition in distinguishing different types of IPCPs.
• To provide insights into the rare and unexpected formation of hetero-IPCPs.

Main Methods:

• Literature review focusing on studies reporting interpenetrating porous coordination polymers.
• Analysis of reported structures to identify key features distinguishing homo- and hetero-IPCPs.
• Categorization of hetero-IPCPs based on similarities and differences in network topology and chemical composition.

Main Results:

• Hetero-IPCPs are characterized by distinct or identical networks in terms of topology and/or chemical composition.
• The rarity of hetero-IPCPs is often linked to specific synthetic conditions or structural constraints.
• A clear distinction between homo- and hetero-IPCPs is established based on defined criteria.

Conclusions:

• Framework topology and chemical composition are crucial for understanding and classifying IPCPs.
• Further research into the synthesis and properties of hetero-IPCPs is warranted due to their unique nature.
• This work provides a framework for identifying and studying rare hetero-IPCPs.
