Cover Picture

20/2001The cover picture shows the molecular structure of the first ferrocene inverse crown complex. Ferrocene, located in the core, has been fourfold deprotonated at the 1,1',3,3'-positions by the encapsulating action of the 16-membered tetrasodium–tetramagnesium amide cationic ring which surrounds it. The perimeter of this ring is highlighted in yellow, the sodium and magnesium atoms are shown in violet and green, respectively. More details on the fascinating structure of this inverse crown complex are described by R. Mulvey et al. on pages 3902 ff.
