Summary
Tetrel elements are key for building stable, larger clusters, especially those with interstitial atoms. This review covers intermetalloid clusters, Zintl phases, and related compounds, highlighting recent advances.
Area of Science:
- Inorganic Chemistry
- Materials Science
- Cluster Chemistry
Background:
- Tetrel elements (e.g., Pb, Sn) are promising for constructing complex clusters.
- Larger clusters exhibit enhanced stability, particularly with interstitial atoms.
- Polyhedral anions form salts, Zintl phases, or intermetallic building blocks.
Purpose of the Study:
- To review the chemistry of intermetalloid clusters.
- To discuss endohedral Zintl ions, Zintl phases, and intermetallic building blocks.
- To contextualize recent findings within metalloid cluster and fullerene research.
Main Methods:
- Literature review of intermetalloid cluster chemistry.
- Focus on selected examples of tetrel-based clusters.
- Discussion of endohedral species and Zintl phases.
Main Results:
- Tetrel-containing clusters, especially with interstitial atoms, demonstrate high stability.
- Diverse structural motifs exist, including Zintl phases and intermetallic compounds.
- Endohedral species and heteroatomic clusters expand the scope of metalloid cluster chemistry.
Conclusions:
- Intermetalloid clusters, particularly those involving tetrels, offer versatile platforms for novel materials.
- The study of Zintl phases and endohedral clusters reveals complex bonding and structural phenomena.
- Continued research in this area promises new insights into metalloid cluster chemistry and related fields.
