Complexation Equilibria: Factors Influencing Stability of Complexes01:09

Complexation Equilibria: Factors Influencing Stability of Complexes

863
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...

Termination of Translation01:44

Termination of Translation

27.8K
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

Electron Transport Chain: Complex III and IV01:43

Electron Transport Chain: Complex III and IV

9.3K
During the electron transport chain, electrons from NADH and FADH2 are first transferred to complexes I and II, respectively. These two complexes then transfer the electrons to ubiquinol, which carries them further to complex III. Complex III passes the electrons across the intermembrane space to Cyt c, which carries them further to complex IV. Complex IV donates electrons to oxygen and reduces it to water. As electrons pass through complexes I, III, and IV, the energy released aids the pumping...

Formation of Complex Ions

26.2K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Crystal Field Theory - Octahedral Complexes

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Area of Science:

  • Coordination Chemistry
  • Organometallic Chemistry
  • Catalysis

Background:

  • Late transition metal oxidants are crucial for C─H bond functionalization via proton coupled electron transfer (PCET).

  • Synthesis and characterization of high-valent metal-cyanate complexes using X-ray crystallography, spectroscopy (UV-vis, NMR, Raman, FT-IR, EPR), and mass spectrometry.
  • Kinetic studies, product analysis, and computational methods to elucidate reaction mechanisms.

Main Results:

  • A novel high-valent copper-cyanate complex, [(L)CuIII(NCO)], was synthesized and characterized.
  • The complex activates C─H and O─H bonds via a hydrogen atom transfer mechanism with rates comparable to known oxidants.
  • Direct C─N bond formation was achieved through C─H activation and cyanate group transfer.
  • Solvent-dependent reactivity was observed.
