Summary
Linear 3d-metal complexes, especially silylamide-based ones, are increasingly understood for their reactivity. This review explores their chemistry, expanding knowledge beyond traditional metal(II) species to lower oxidation states.
Area of Science:
- Coordination Chemistry
- Organometallic Chemistry
- Materials Science
Background:
- Linear 3d-metal complexes with open-shell metal ions have been studied for decades.
- Initial research focused on metal(II) species, but reduced analogues and N-heterocyclic carbenes (NHCs) expanded accessible oxidation states to +I and 0.
- Despite structural data, reactivity and catalytic applications were limited due to compound lability.
Purpose of the Study:
- To review the emerging chemistry and reactivity of silylamide-based linear metal complexes.
- To provide a comprehensive overview of their reactivity patterns.
- To serve as an entry point for chemists interested in this field.
Main Methods:
- Literature review of silylamide-based linear metal complexes.
- Inclusion of selected reactivity examples from other linear metal complexes.
- Focus on recent developments in understanding reactivity patterns.
Main Results:
- Silylamide-based species show a developing comprehensive picture of their reactivity.
- Expanded understanding of accessible oxidation states beyond metal(II).
- Demonstrated potential for broader applications through enhanced stability and reactivity.
Conclusions:
- The chemistry of linear 3d-metal complexes, particularly silylamide-based ones, is rapidly advancing.
- These compounds offer new avenues for reactivity and potential catalytic applications.
- The review encourages further exploration and participation in this research area.

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...

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...

Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

02:26Preparation and Reactions of Sulfides
5.1K
Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.

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.

02:42Valence Bond Theory
9.2K
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...
