A cubic diamond lattice metal-organic framework
| Background
Synthesized metal-organic frameworks have been shown to have a wide range of applications, as 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; the CSD entry JARMEU.
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.
A cubic diamond lattice metal-organic framework
Shown at the right is the building block of the lattice (restore initial scene).
When the repeats of this building block are shown connected to others, the lattice appears. Viewing the the CSD entry JARMEU as a 1x1x3 set of the metal organic framework illustrates this.
When considered this way a beautiful diamondoid structure appears that is a 4-connected network.
The large cavities are visible as the lattice layers onto itself as the view of the structure rotates.
The extensive nature becomes more apparent if we consider more of the lattice.
The CSD entry JARMEU as a 1x3x3 plane of the metal organic framework. (Substatntial patience required when loading this scene; it is suggested to only do that after you have examined the others.)

Significance
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
safety, and drug delivery & diagnostics/therapy have been demonstrated[1].
Technical Details
The views featuring the 1x1x3 set and the plane were built using the Jmol Crystal Symmetry Explorer to examine CSD Entry: JARMEU.

A catalytic molybdenum metal-organic framework
| Background
Metal-organic frameworks have been shown to be applicable to catalysis, among many other applications, as highlighted three chemists doing seminal work in this field being awarded the Nobel Prize in Chemistry in 2025.
A catalytic molybdenum metal-organic framework was synthesized from porphyrin and sodium molybdate dihydrate by a hydrothermal method.
The framework was characterized and shown to catalyze oxidation of cyclohexene.
Here the crystal structure of catalytic molybdenum metal-organic framework is featured.
