Summary
A novel mixed-ligand gold complex with asymmetric properties was synthesized. This complex exhibits enhanced electrochemical and optical band gaps compared to its symmetric precursors.
Area of Science:
- Organometallic Chemistry
- Materials Science
- Coordination Chemistry
Background:
- Dithiolene complexes are known for their unique electronic and optical properties.
- Symmetric radical complexes offer a platform for developing novel materials.
Purpose of the Study:
- To synthesize and characterize a mixed-ligand bis(dithiolene) gold complex.
- To investigate the impact of asymmetric character on the complex's properties.
Main Methods:
- Scrambling reaction of two neutral radical symmetric complexes.
- Isolation and structural characterization of the resulting mixed-ligand complex.
- Electrochemical and optical measurements.
Main Results:
- Successful isolation of a mixed-ligand bis(dithiolene) gold complex.
- The asymmetric complex displays distinct structural and electronic properties.
- Larger electrochemical and optical band gaps were observed compared to precursors.

22.9K
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...

01:16Radical Reactivity: Nucleophilic Radicals
2.4K
Radicals adjacent to electron-donating groups are called nucleophilic radicals. These radicals readily react with electrophilic alkenes. The SOMO–LUMO interactions are the driving force for the reaction, where the high-energy SOMO of the electron-rich, nucleophilic radicals interacts with the low-energy LUMO of the electron-deficient, electrophilic alkenes. Such SOMO–LUMO interactions are the basis of reactive radical traps, affecting the selectivity in radical reactions. For...

01:19Complexation Equilibria: The Chelate Effect
879
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...

02:42Valence Bond Theory
10.2K
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...

01:11Radical Reactivity: Overview
2.4K
Radicals, the highly reactive species, gain stability by undergoing three different reactions. The first reaction involves a radical-radical coupling, in which a radical combines with another radical, forming a spin‐paired molecule. The second reaction is between a radical and a spin‐paired molecule, generating a new radical and a new spin‐paired molecule. The third reaction is radical decomposition in a unimolecular reaction, forming a new radical and a spin‐paired...

01:26Radical Substitution: Hydrogenolysis of Alkyl Halides with Tributyltin Hydride
2.1K
Radical substitution reactions can be used to remove functional groups from molecules. The hydrogenolysis of alkyl halides is one such reaction, where the weak Sn–H bond in tributyltin hydride reacts with alkyl halides to form alkanes. Here, the reagent Bu3SnH yields tributyltin halide as a byproduct.
The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation reactions,...
