Iron sulfur clusters can be categorized based on their nuclearity and structural arrangement. Common types include: - Fe-S: Simple binary compounds, such as FeS or FeS2 (pyrite). - Fe-S-Cu: Ternary clusters like Fe2S2(Cu). - Fe-S-C: Compounds incorporating carbon atoms, such as [Fe4S4(Cys)4] found in some enzymes. Each type exhibits unique catalytic properties and is suited for specific applications.
