Properties of Organometallic Compounds

Properties of Organometallic Compounds

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.

Structural Isomerism

Structural Isomerism

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...

Metal-Ligand Bonds

Metal-Ligand Bonds

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...

Ionic Crystal Structures

Ionic Crystal Structures

Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Lewis Structures of Molecular Compounds and Polyatomic Ions

To draw Lewis structures for complicated molecules and molecular ions, it is helpful to follow a step-by-step procedure as outlined:

Valence Bond Theory

Valence Bond Theory

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...

Background:

Metal-organic frameworks (MOFs) are advanced materials with tunable properties.
The isoreticular approach is crucial for modifying MOF characteristics like pore size and linker functionality.

Purpose of the Study:

To demonstrate the formation of isoreticular MOFs using linkers with both phosphonate and phosphinate coordinating groups.
To expand the synthetic strategies for creating diverse MOFs.

Main Methods:

Synthesis of a novel bifunctional ligand, 4-[hydroxy(methyl)phosphoryl]phenylphosphonic acid [H3PPP(Me)].
Preparation of MOFs using the bifunctional ligand and 1,4-benzenediphosphonic acid.
Characterization of the resulting MOFs (ICR-12 and ICR-13) for structural and chemical properties.

Main Results:

Successfully synthesized ICR-12, a metal-organic framework (MOF) isoreticular to known bisphosphinate MOFs, using a novel bifunctional phosphonate-phosphinate ligand.
Prepared ICR-13, an isostructural MOF, using 1,4-benzenediphosphonic acid.
Demonstrated that linkers with mixed coordinating groups can be effectively used in the isoreticular design of MOFs.

Conclusions:

The developed strategy successfully bridges the gap between phosphinate and phosphonate-based MOFs.
This approach significantly broadens the scope of accessible MOF structures and functionalities.
The findings pave the way for the rational design of a wider range of advanced MOFs.
