Summary
Anion-templated silver nanoclusters offer precise control over size, shape, and functionality. This review explores synthesis methods and the impact of various anions on silver nanocluster structures.
Area of Science:
- Materials Science
- Nanotechnology
- Inorganic Chemistry
Background:
- Metal nanoclusters (NCs) exhibit unique size-specific properties distinct from bulk metals.
- Silver nanoclusters (Ag NCs) can be synthesized as pure or anion-templated structures.
- Anion-templated Ag NCs offer tunable size, shape, stability, and functionality.
Purpose of the Study:
- To review synthesis methods for anion-templated Ag NCs.
- To elucidate the influence of central anions on the geometric structure of Ag NCs.
- To provide a reference for developing novel anion-templated Ag NCs.
Main Methods:
- Review of synthesis strategies for anion-templated Ag NCs.
- Analysis of the role of central anions (halides, chalcogenides, oxoanions, polyoxometalates, hydride/deuteride) in structural determination.
- Correlation of anion properties with Ag NC geometric structure and stability.
Main Results:
- Diverse central anions (halide, chalcogenide, oxoanion, polyoxometalate, hydride/deuteride) enable precise control over Ag NC synthesis.
- The central anion dictates size, shape, and stabilization mechanisms of Ag NCs.
- Specific anion choices lead to predictable geometric structures and physicochemical properties.
Conclusions:
- Anion templating is a powerful strategy for designing Ag NCs with tailored properties.
- Understanding anion-metal interactions is key to advancing Ag NC research.
- This review facilitates the development of new anion-templated Ag NCs with enhanced functionalities.

Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

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...
