Summary
Novel silver clusters were synthesized using anion templates like V10O28(6-) and SO4(2-), with varying carboxylate ligands controlling their structure and properties.
Area of Science:
- Inorganic Chemistry
- Materials Science
- Nanotechnology
Background:
- Anion templates play a crucial role in directing the assembly of novel inorganic clusters.
- Carboxylate ligands offer versatility in modifying the structure and properties of metal-based clusters.
- Exploring new synthetic routes for complex silver thiolated clusters is an active area of research.
Purpose of the Study:
- To synthesize and characterize novel anion-templated silver thiolated clusters using different carboxylate ligands.
- To investigate the influence of anion templates (V10O28(6-) and SO4(2-)) and carboxylate ligands on cluster assembly.
- To explore the structural diversity and electrochemical properties of the synthesized silver clusters.
Main Methods:
- Solvothermal synthesis conditions were employed to generate anion templates in situ.
- Single-crystal X-ray diffraction was used to determine the crystal structures of the synthesized clusters.
- Electrochemical properties of the resulting silver clusters were analyzed.
Main Results:
- Three novel anion-templated silver thiolated clusters were successfully synthesized: V10O28@Ag46(iPrS)28(CF3CO2)12(DMF)2 (1), V10O28@Ag46(iPrS)30(CF3CO2)8(PhCO2)2(DMF)4 (2), and [SO4@Ag20(iPrS)10(PTA)3(HPTA)2] (3).
- Clusters 1 and 2 feature discrete V10O28@Ag46 structures, with cluster 2 exhibiting different organic shells due to the addition of PhCO2H.
- Cluster 3 presents a unique three-dimensional (3D) structure containing the SO4(2-) template, formed with the addition of H2PTA.
Conclusions:
- This study reports the first synthesis of heterogeneous silver clusters incorporating the V10O28(6-) anion template with isopropyl thiolate ligands.
- A novel Ag20 cluster with a 3D structure templated by SO4(2-) was successfully obtained.
- The findings highlight the significant impact of carboxylic acids on the assembly process of silver clusters, suggesting further exploration is warranted.

23.9K
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...

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...

01:19Complexation Equilibria: The Chelate Effect
623
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...

Polydentate ligands are most widely used in complexometric titrations because they form more stable complexes with the metal ions than mono- or bidentate ligands due to the chelate effect. Examples of polydentate ligands are ethylenediaminetetraacetic acid (EDTA), crown ethers, and cryptands. The most important feature of optimal polydentate ligands is the ability to form 1:1 complexes in a single-step process. Amino carboxylic acid derivatives are frequently used as complexing agents. EDTA is...

01:09Complexation Equilibria: Factors Influencing Stability of Complexes
459
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...

1.1K
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...
