Metal-Ligand Bonds02:51

Metal-Ligand Bonds

25.6K
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...

Valence Bond Theory02:42

Valence Bond Theory

11.7K
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...

Complexation Equilibria: The Chelate Effect01:19

Complexation Equilibria: The Chelate Effect

1.6K
In complexation reactions, metal atoms or cations interact with ligands to form donor-acceptor adducts called metal complexes. Ligands that bind through one donor site are monodentate, ligands with two donor sites are bidentate, and those with more than two donor sites are polydentate ligands. For example, ethylene diamine is a bidentate ligand that binds through two nitrogen donor atoms, forming a five-membered ring. EDTA is a polydentate ligand that binds through four oxygen and two nitrogen...

Complexation Equilibria: Factors Influencing Stability of Complexes01:09

Complexation Equilibria: Factors Influencing Stability of Complexes

967
In complexation reactions, metal cations are the electron pair acceptors, and the ligands are the electron pair donors. The stability of the metal complexes depends primarily on the complexing ability of the central metal ion and the nature of the ligands. Generally, the complexing ability of the metal ion depends on the size and charge of the ion. As the metal ion size increases, the stability of the metal complexes decreases, provided that the valency of the metal ion and the ligands remain...

Complexometric Titration: Ligands00:43

Complexometric Titration: Ligands

2.6K
Different monodentate and polydentate ligands are used as complexing agents in complexometric titration reactions. The formation of complexes by mono- and bidentate ligands involves two or more intermediate steps, limiting their use as complexing agents. In comparison, polydentate ligands can form complexes with metal ions in a single-step process, facilitating sharper end points. This means polydentate ligands, such as amino carboxylic acid derivatives, are most commonly employed in...

Colors and Magnetism03:02

Colors and Magnetism

14.6K
Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Area of Science:

  • Catalysis
  • Organometallic Chemistry
  • Coordination Chemistry

Background:

  • Metal-ligand cooperation (MLC) is a key concept in transition metal catalysis.
  • Unlike traditional catalysis, MLC involves direct participation of both metal and ligand in bond activation.
  • This contrasts with spectator ligands that do not directly engage in catalytic transformations.

Purpose of the Study:

  • To review examples of metal-ligand cooperation in catalysis.
  • To discuss MLC mechanisms involving chemical modification of both metal and ligand.
  • To explore MLC's role in both catalytic enhancement and deactivation.

Main Methods:

  • Literature review of existing studies on metal-ligand cooperation.
  • Analysis of catalytic systems demonstrating MLC.
  • Discussion of theoretical and experimental evidence for MLC mechanisms.

Main Results:

  • Identified two main types of MLC: direct chemical modification and indirect coordination sphere changes.
  • Highlighted MLC's dual role in promoting effective catalysis and causing catalyst deactivation.
  • Provided examples of MLC in synthetic and biological systems.

Conclusions:

  • Metal-ligand cooperation is a versatile concept with significant implications for catalyst design.
  • Understanding MLC is essential for developing efficient and stable catalytic systems.
  • MLC influences both the activity and longevity of transition metal catalysts.
