Summary
We report a disordered metal-organic framework (MOF) that maintains porosity and open metal sites, crucial for applications like gas storage and catalysis. This disordered MOF-74 material shows promise despite lacking traditional crystalline structure.
Area of Science:
- Materials Science
- Chemistry
Background:
- Metal-organic frameworks (MOFs) are crystalline porous materials with diverse applications.
- MOF-74 is a well-known MOF family, typically crystalline, used for gas adsorption.
Purpose of the Study:
- To report the synthesis and characterization of an intrinsically disordered MOF within the MOF-74 family.
- To investigate the structural, porous, and metal site properties of this novel disordered material.
Main Methods:
- Synthesis of Mg2-x(as-dobpdc) material.
- Characterization using techniques to assess crystallinity, porosity, and metal site accessibility.
Main Results:
- An intrinsically disordered MOF, Mg2-x(as-dobpdc), was successfully synthesized.
- The material exhibits local ordering despite the absence of long-range crystallinity.
- Porosity and a high density of open metal sites were maintained.
Conclusions:
- Disordered MOFs can retain key functional properties like porosity and open metal sites.
- This finding expands the design possibilities for MOFs beyond crystalline structures.
- The disordered MOF-74 material shows potential for applications requiring accessible metal sites.

Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

02:37Metallic Solids
18.7K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

02:42Valence Bond Theory
9.7K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

01:23Properties of Organometallic Compounds
1.1K
Organometallic compounds are compounds that contain a carbon–metal bond. Carbon belongs to an organyl group like alkyl, aryl, allyl, or benzyl groups. The metal can be from Group I or Group II of the periodic table, a transition metal, or a semimetal.

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
