Resumen
Los complejos metálicos lineales 3d, especialmente los basados en silílamida, se comprenden cada vez más por su reactividad. Esta revisión explora su química, expandiendo el conocimiento más allá de las especies tradicionales de metal (II) a estados de oxidación más bajos.
Área de la Ciencia:
- Química de coordinación
- Química organometálica
- Ciencias de los materiales
Sus antecedentes:
- Los complejos metálicos 3D lineales con iones metálicos de caparazón abierta se han estudiado durante décadas.
- La investigación inicial se centró en las especies metálicas, pero los análogos reducidos y los carbenos N-heterocíclicos (NHC) ampliaron los estados de oxidación accesibles a +I y 0.
- A pesar de los datos estructurales, la reactividad y las aplicaciones catalíticas fueron limitadas debido a la labilidad del compuesto.
Objetivo del estudio:
- Revisar la química emergente y la reactividad de los complejos metálicos lineales basados en sililamida.
- Proporcionar una visión general de sus patrones de reactividad.
- Servir como punto de entrada para los químicos interesados en este campo.
Principales métodos:
- Revisión de la literatura sobre los complejos metálicos lineales basados en silalamida.
- Incluir ejemplos de reactividad seleccionados de otros complejos metálicos lineales.
- Centrarse en los desarrollos recientes en la comprensión de los patrones de reactividad.
Principales resultados:
- Las especies basadas en sililamida muestran un panorama completo de su reactividad.
- Comprensión ampliada de los estados de oxidación accesibles más allá del metal (II).
- Potencial demostrado para aplicaciones más amplias a través de una mayor estabilidad y reactividad.
Conclusiones:
- La química de los complejos metálicos lineales, en particular los basados en silílamida, está avanzando rápidamente.
- Estos compuestos ofrecen nuevas vías para la reactividad y potenciales aplicaciones catalíticas.
- La revisión fomenta una mayor exploración y participación en esta área de investigación.

02:51Metal-Ligand Bonds
21.5K
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...
