The resurgence of the C 5 ligand in main group chemistry: Recently Harder et al. ( Angew. Chem. Int. Ed. Engl. 1994 , 33 , 1744) have synthesized and structurally characterized the lithocene anion 1 , the simplest sandwich complex, and Hanusa et al. ( Angew. Chem. Int. Ed. Engl. 1994 , 33 , 2191) have prepared the “open” calcocene 2 , an alkaline‐earth metal complex with a remarkable structure. Such compounds are not only of significance for bonding theory, they are also interesting as precursors for important industrial processes.
