Abiological iron-sulfur clusters

Article Abstract:

Iron-sulfur clusters are significant because they comprise a major group in metal cluster chemistry. Several such clusters have already been synthesized and structurally examined, and their properties have been investigated extensively. Synthesis of iron-sulfur clusters can be performed using one of five common techniques. Those clusters with organic supporting ligands feature three to seven iron atoms in the cluster core. Based on the number of these iron atoms, iron-sulfur clusters can be classified into triiron clusters, tetrairon clusters, cubane clusters, and pentairon and higher nuclearity clusters.

Reactions of transition metal complexes with fullerenes (C60, C70, etc.) and related materials

Article Abstract:

Reactions between fullerenes and transition metal complexes and fullerenes are reviewed. These reactions generate different new compounds. The addition of metal to the olefinic C-C bonds at 6:6 ring junctions generate eta-squared-coordination complexes. Decreasing the level of fullerene creates fulleride salts while adding ligating groups to the fullerene produces a metal center connected to the fullerene. Meanwhile, solids can be formed when the fullerene and a metal complex are cocrystallized. Isolated fullerene complexes across the periodic table are reviewed.
