1Department of Chemistry and Chemical Biology, Harvard University , Cambridge, Massachusetts 02138, United States.
Synthetic iron-sulfur clusters exhibit diverse structures and reactivity. This study highlights cluster conversions, where iron-sulfur cores transform into new structures, offering insights into their modular nature and biological relevance.
Area of Science:
- Inorganic Chemistry
- Bioinorganic Chemistry
- Materials Science
Background:
- Synthetic iron-sulfur clusters ([FemSqLl]z) possess diverse structures, some mimicking those in proteins.
- Previous research predominantly focused on the physical properties of these clusters.
Purpose of the Study:
- To investigate the reactivity of synthetic iron-sulfur clusters, specifically focusing on cluster conversion reactions.
- To present a comprehensive overview of core conversions, including those occurring in biological systems.
Main Methods:
- Systematic presentation and depiction of various structural core types.
- Diagrammatic summarization of identified core conversion pathways.
- Analysis of reactions such as self-assembly, fragment condensation, and dissociation.
Main Results:
- Identified and presented an extensive body of iron-sulfur cluster core conversions, many previously unrecognized.
- Highlighted the central role of the cubane-type Fe4S4 core in conversion chemistry.
- Demonstrated that iron-sulfur cores can be viewed as modular units undergoing transformations.
Conclusions:
- Iron-sulfur cluster core conversions represent a significant aspect of their reactivity.
- The modular nature of iron-sulfur cores facilitates transformations into diverse structures.
- Understanding these conversions provides new perspectives on iron-sulfur cluster chemistry in both synthetic and biological contexts.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
