Cover Picture (Angew. Chem. Int. Ed. 5/1999)

38_05/1999The cover picture shows the structure of the trihydroxycarbenium ion, as determined by a crystal structure investigation. By reaction in superacids, salts with the general composition C(OH)3+ MF6 (M - As, Sb) of the nonexistent carbonic acid could be isolated. These compounds demonstrate the synthesis potential of superacidic systems and their importance for the experimental proof and structural characterization of cationic intermediates. A transfer of the synthesis principle presented here to other systems is conceivable. More about these interesting salts is reported by R. Minkwitz and S. Schneider on pages 714 ff. The cover picture was generated by F. Neikes using POV-Ray, version 3, 1997.
