==A Metal–organic framework structure==

Synthesized metal-organic frameworks have been shown to have a wide range of applications, as [[Proteopedia:Hot_News|highlighted three chemists doing seminal work in this field being awarded the Nobel Prize in Chemistry in 2025]].

Here the crystal structure of a cubic diamond metal-organic framework is featured; [https://www.ccdc.cam.ac.uk/structures/Search?Ccdcid=JARMEU&DatabaseToSearch=CSD the CSD entry JARMEU]<ref>B.F. Hoskins and R. Robson. 1989. Infinite polymeric frameworks consisting of three dimensionally linked rod-like segments. Journal of the American Chemical Society, v111, pg. 5962-5964, [https://pubs.acs.org/doi/abs/10.1021/ja00197a079 |DOI: 10.1021/ja00197a079]</ref>. <br/>

This is the structure that revealed that a crystalline, diamondoid, extended framework was formed that had large cavities, establishing this class of solid polymeric materials.

The cavities would contain anions and solvent that are not shown in this crystal structure as they'd be freely moving and randomly distributed.

Since the proposal of this class of materials, metal-organic framework have been proven to support many roles. Applications to gas storage, analytical chemistry and (bio)sensors, batteries and fuel cell technology, separation science, synthesis and catalysis, harvesting of water from dry (low humidity) air, water purification and environmental remediation, capture/destruction of harmful agents, energy conversion and storage, hydrogen generation, food
