23_11/1984The cover page shows the structure of the Fe8S6I83⊖ ion. The eight iron atoms form an almost ideal cube; the six μ4-bonded sulfur atoms over the faces of the cube result in an almost regular dodecahedron with twelve rectangular faces. The iron atoms are coordinated in a slightly distorted tetrahedral fashion with respect to the terminal iodine atoms. The synthesis, structure, and importance of this interesting cluster ion as a model for the active center of the FeMo-protein of nitrogenase are discussed by S. Pohl and W. Saak in their communication on p. 907f.
